A 4.0 kg mass is 1.0 m away from a 7.0 kg mass. What is the gravitational force between the two masses? (Remember to use the gravitational constant, G = 6.67 x 10-11 N x m2/ kg2, in your calculation.)

6.67 x 10 -11 N
1.9 x 10 -9N
6.67 x 10 10N
3.8 N

Answers

Answer 1

The gravitational force between the two masses is approximately 1.96 x 10⁻⁹ N. Option B is correct.

The gravitational force between two masses can be calculated using the formula;

F=G x (m₁ x m₂) / r²

Where F is the gravitational force, G is the gravitational constant, m₁ and m₂ are the masses of the two objects, and r is the distance between their centers of mass.

In this case, m₁ = 4.0 kg, m₂ = 7.0 kg, r = 1.0 m, and G = 6.67 x 10⁻¹¹ N x m²/kg². Plugging these values into the formula gives;

F = (6.67 x 10⁻¹¹ N x m²/kg²) x (4.0 kg x 7.0 kg) / (1.0 m)²

F = 1.96 x 10⁻⁹ N

Therefore, the gravitational force is 1.96 x 10⁻⁹ N.

Hence, B. is the correct option.

A diverging lens has a focal length of -12. 8cm. An object is placed 34. 5cm from the len’s surface: Determine the image distance

Answers

The image distance formed by the diverging lens is 9.335cm.

To determine the image distance formed by a diverging lens with a focal length of -12.8cm, we can use the thin lens formula:

1/f = 1/do + 1/di

where f is the focal length of the lens, do is the distance from the object to the lens, and di is the distance from the lens to the image.

Substituting the given values, we get:

1/-12.8cm = 1/34.5cm + 1/di

Simplifying and solving for di, we get:

1/di = 1/-12.8cm - 1/34.5cm

1/di = -0.078125 cm^-1 - 0.02898550724637681 cm^-1

1/di = -0.1071105072463768 cm^-1

di = 9.335 cm

It's worth noting that the negative sign for the focal length indicates that the lens is a diverging lens.

The positive sign for the object distance indicates that the object is located on the same side of the lens as the incident light,

while the negative sign for the image distance indicates that the image is formed on the opposite side of the lens as the incident light, which is typical for a diverging lens.

A cubic container is at rest on a rough horizontal warehouse floor. if the mass of the container is 60.6 kg and the coefficient of static friction is 0.570, determine the minimum horizontal force that must be applied to the top of the container to cause tipping.

Answers

To determine the minimum horizontal force that must be applied to the top of the container to cause tipping, we need to use the concept of torque. Torque is a force that causes rotation and is defined as the product of the force and the perpendicular distance from the point of rotation. In this case, the point of rotation is the edge of the container in contact with the floor.

Firstly, we need to find the weight of the container which is given by the mass times the acceleration due to gravity (9.8 m/s^2). Thus, the weight of the container is 593.88 N.

Next, we need to find the maximum force of static friction that the floor can exert on the container to prevent it from tipping. This is given by the coefficient of static friction (0.570) times the weight of the container (593.88 N). Thus, the maximum force of static friction is 338.73 N.

To cause tipping, a force must be applied to the container in such a way that it produces torque. This torque must overcome the torque produced by the force of static friction. The torque produced by the force of static friction is equal to the product of the maximum force of static friction and the distance from the point of rotation to the line of action of the force of static friction, which is half the height of the container (0.5 m).

Thus, the minimum horizontal force that must be applied to the top of the container to cause tipping is the force required to produce a torque equal to the torque produced by the force of static friction. This is given by the equation:

force x distance = maximum force of static friction x 0.5
Solving for force, we get:
force = (maximum force of static friction x 0.5) / distance

Substituting the values, we get:
force = (338.73 N x 0.5) / 0.6 m
force = 282.27 N

Therefore, the minimum horizontal force that must be applied to the top of the container to cause tipping is 282.27 N.

In conclusion, the minimum horizontal force required to tip the container depends on the coefficient of static friction and the distance between the point of rotation and the line of action of the force. In this case, the force required is 282.27 N, which must be applied at a distance of 0.6 m from the point of rotation.

As soil particle size decreases from silt to clay, the field capacity __________ and the available water __________.

Answers

As soil particle size decreases from silt to clay, the field capacity typically increases and the available water decreases.

This is because as particle size decreases, the pore spaces between particles also decrease, which in turn decreases the amount of water that can be held in the soil.

However, the smaller pore spaces also increase the surface area available for water to adhere to soil particles, resulting in a higher field capacity.

Field capacity is the amount of water held in the soil after excess water has drained away, and it is affected by factors such as soil texture, structure, and organic matter content.

Available water is the amount of water that plants can extract from the soil, and it is influenced by factors such as the depth of the plant roots and the water-holding capacity of the soil.

Overall, understanding the relationship between soil particle size and water retention is important for effective irrigation and soil management practices.

We can observe total internal reflection when light travels (n_glass = 1 50.flower = 1.33) a. from glass to water b. from water to glass c. from air to glass

Answers

We can observe total internal reflection when light travels from air to glass, but not from glass to water or from water to glass. This is because in those cases, the light is traveling from a higher refractive index medium to a lower one, and thus there is no opportunity for internal reflection.

Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence is greater than the critical angle. In this case, n_glass = 1.50 and n_water = 1.33.
a. From glass to water: Total internal reflection can occur as the light is moving from a higher refractive index (glass) to a lower refractive index (water).
b. From water to glass: Total internal reflection cannot occur as the light is moving from a lower refractive index (water) to a higher refractive index (glass).
c. From air to glass: Total internal reflection cannot occur as the light is moving from a lower refractive index (air) to a higher refractive index (glass).

The vast majority of stars in a newly formed star cluster are __________. red giants very high-mass, type o and b stars less massive than the sun about the same mass as our sun

Answers

The vast majority of stars in a newly formed star cluster are less massive than the sun, and about the same mass as our sun.

In a newly formed star cluster, most stars are categorized as low-mass or medium-mass stars, similar in size to our sun. This is because the process of star formation results in a mass distribution that follows a pattern called the initial mass function (IMF).

The IMF indicates that lower mass stars are much more abundant than high-mass stars.

High-mass, Type O and B stars, as well as red giants, are not as common in newly formed star clusters. Type O and B stars are very massive, hot, and luminous, but their rarity is due to the fact that they consume their nuclear fuel at a rapid rate, leading to shorter lifespans.

Red giants are also relatively rare in new star clusters, as they represent a later evolutionary stage of lower-mass stars, such as those with masses similar to our sun.

In summary, the vast majority of stars in a newly formed star cluster are less massive than the sun and about the same mass as our sun. High-mass, Type O and B stars, and red giants are less common in these clusters.

A roller coaster passes over the top of the hill going 2. 7 m/s and reacts the bottom going 14m/s


A)How high is the hill?


B)What is spread half way down?


(Energy problem)

Answers

The height of the hill will be h' = (1/2)(v_i^2)/g

The spread halfway down is equal to half of the initial potential energy of the roller coaster at the top of the hill.

The spread halfway down is equal to half of the initial potential energy of the roller coaster at the top of the hill.

To solve this energy problem, we can utilize the principles of conservation of energy. The total mechanical energy of the roller coaster, consisting of its potential energy (PE) and kinetic energy (KE), remains constant throughout the ride.

A) To determine the height of the hill, we can equate the initial and final mechanical energies of the roller coaster at the top and bottom of the hill, respectively.

At the top of the hill:

Initial mechanical energy (E_i) = PE_i + KE_i = mgh + (1/2)mv_i^2

At the bottom of the hill:

Final mechanical energy (E_f) = PE_f + KE_f = mgh' + (1/2)mv_f^2

Since the roller coaster is at the top of the hill, its final kinetic energy (KE_f) is zero because it has come to a stop momentarily. Therefore, we have:

E_i = PE_i + KE_i = PE_f + KE_f = mgh + (1/2)mv_i^2 = mgh'

We are given that the roller coaster's initial velocity at the top of the hill (v_i) is 2.7 m/s, and its final velocity at the bottom (v_f) is 14 m/s.

Substituting these values into the equation, we get:

(1/2)mv_i^2 = mgh'

Simplifying and solving for h', the height of the hill, we have:

h' = (1/2)(v_i^2)/g

where g is the acceleration due to gravity (approximately 9.8 m/s^2).

B) To find the spread halfway down, we need to calculate the difference in potential energy between the top and halfway down the hill.

The potential energy at the top of the hill (PE_i) is given by mgh, and the potential energy halfway down (PE_half) is given by (1/2)mgh.

The spread halfway down is the difference between these two potential energies:

Spread halfway down = PE_i - PE_half = mgh - (1/2)mgh = (1/2)mgh

Therefore, the spread halfway down is equal to half of the initial potential energy of the roller coaster at the top of the hill.

no drag force between the boat and water, and that there is no net external force applied to the system.


What happens to the boat?

Answers

As the fisherman walks towards the shore on the boat, the boat moves away from the shore to maintain the center of mass of the fisherman-boat system.

When the fisherman (mass m) stands at the center of the small boat (also mass m) and walks towards the shore, the following occurs:

1. As the fisherman moves towards the shore, he exerts a force on the boat in the opposite direction, due to Newton's Third Law of Motion (action and reaction forces are equal and opposite).

2. The boat will move away from the shore in response to the force exerted by the fisherman's movement. This is because the fisherman-boat system is initially stationary, and there is no net external force acting on it.

3. The center of mass of the fisherman-boat system remains constant. This means that as the fisherman moves closer to the shore, the boat must move further away from the shore to maintain the same center of mass.

4. When the fisherman stops walking, the boat will also stop moving away from the shore, but at a greater distance than initially. The fisherman and the boat would have moved relative to each other, but their combined center of mass remains at the same distance (d) from the shore.

what needs to happen to the index of refraction to produce a rainbow

Answers

To produce a rainbow, the index of refraction needs to vary with wavelength, which causes the different colors of light to refract at slightly different angles.

This occurs when light enters a water droplet and is bent, or refracted, as it slows down due to the higher index of refraction of water compared to air. The different colors of light then reflect off the inner surface of the droplet and are refracted again as they exit the droplet, creating a spectrum of colors. This process is called dispersion and is what creates the beautiful colors of a rainbow.

The tension on the rope is 886 N. We can use Newton's second law to solve this problem:

ΣF = ma

where

ΣF is the net force acting on the hero,

m is the mass of the hero, and

What angular acceleration would be required in order to stop the earth from rotating over a period of 30.0 minutes

Answers

The angular acceleration required to stop the rotation of the Earth over a period of 30 minutes would be equal to the final angular velocity divided by the time interval.

The Earth's rotation is an example of rotational motion, which is described by angular velocity and angular acceleration. Angular velocity is the rate of change of angular displacement with respect to time, and angular acceleration is the rate of change of angular velocity with respect to time.  

The final angular velocity would be zero, since the Earth would have stopped rotating, and the initial angular velocity can be calculated by dividing the circumference of the Earth (40,075 km) by the time period of 24 hours or 1,440 minutes, which gives a value of approximately 0.28 degrees per minute.

Therefore, the initial angular velocity would be (0.28 degrees/minute)(2pi radians/360 degrees) = 0.00489 radians/minute. Dividing this value by 30 minutes gives an angular acceleration of approximately 0.000163 radians/(minute²).

Answers

The distance between two consecutive staples in the finished part is approximately 0.28 meters or 28.46 centimeters.

Consider the relative velocity between the staple gun and the parts to be stapled.

The staple gun is rolling to the left at 1.5 m/s, while the parts are rolling to the right at 2.2 m/s. Therefore, the relative velocity between the staple gun and the parts is:

v_rel = v_parts - v_staple_gun = 2.2 m/s - (-1.5 m/s) = 3.7 m/s

The staple gun fires 13 staples per second, so the time between two consecutive staples is:

t = 1/13 s

During this time, the relative velocity between the staple gun and the parts causes the distance between the two consecutive staples in the finished part. Let's call this distance "d".

Answers

The woman did work on the laundry basket by lifting it and carrying it. The total work done was 547J when she lifted it 1.5m and carried it 20m in 15 seconds.

The work done by the woman on the laundry basket can be calculated by finding the force required to lift the basket and carry it across the room, and then multiplying that force by the distance covered. Work is defined as the product of force and displacement in the direction of the force.

To lift the laundry basket up 1.5m, the woman needs to exert a force equal to the weight of the basket, which can be calculated as mass times gravity. Assuming the basket has a mass of 10kg, the force required to lift it is 98N. The work done in lifting the basket is therefore W = Fd = 98N x 1.5m = 147J.

To carry the basket 20m across the room, the woman needs to exert a force equal to the weight of the basket plus any additional force required to overcome friction.

Assuming the coefficient of friction between the basket and the floor is 0.2, the force required is approximately 20N. The work done in carrying the basket is therefore W = Fd = 20N x 20m = 400J.

The total work done by the woman on the laundry basket is the sum of the work done in lifting it and the work done in carrying it, which is 147J + 400J = 547J.

Therefore, the total work done by the woman on the laundry basket as she lifts it up 1.5m and carries it 20m across the room in 15 seconds is 547J.

Which of these is NOT considered an example of low EM energy?
A. infra-red
B. microwaves
C. ultra-violet
D. radio waves​

Answers

ultra-violet is NOT considered an example of low Electromagnetic energy. Hence option C is correct.

Electromagnetic waves, which are synchronised oscillations of the electric and magnetic fields, are the traditional form of electromagnetic radiation. The electromagnetic spectrum is created at various wavelengths depending on the oscillation frequency. Electromagnetic waves move at the speed of light, typically abbreviated as c, in a vacuum. The oscillations of the two fields create a transverse wave in homogeneous, isotropic media when they are perpendicular to each other, perpendicular to the direction of energy and wave propagation, and perpendicular to each other. Either an electromagnetic wave's oscillation frequency or its wavelength can be used to describe its location within the electromagnetic spectrum. Because they come from different sources and have different effects on matter, electromagnetic waves of different frequencies are known by various names. These are listed in decreasing wavelength and increasing frequency order: sound waves, lower energy have lower frequency.

Answers

His results appear to be accurate and reasonable.

Yes, Chayse's results are reasonable. The frequency and wavelength of ultraviolet (UV) rays fall within the appropriate range of values for this type of electromagnetic radiation.

UV rays have higher frequencies and shorter wavelengths than visible light, and their frequencies typically range from about 7.5 × 10^14 Hz to 3 × 10^16 Hz, while their wavelengths range from about 10 nm to 400 nm. Chayse's measured frequency of 1.53 × 10^16 Hz and wavelength of 1.96 × 10^-8 m are consistent with these values for UV rays.

Assuming birdman flies at a speed of 37m/s,how high should birdman fly to hit the bucket if the bucket is placed 118m from the start of the field

Answers

Birdman needs to fly at a height of 49.05m to hit the bucket placed 118m away from the start of the field, assuming he flies at a speed of 37m/s.

Birdman's required height

To calculate the height at which Birdman needs to fly to hit the bucket, we need to use the equations of motion and consider the horizontal and vertical components separately.

Let's assume that Birdman is launching himself horizontally from the start of the field and needs to hit the bucket at a distance of 118m. We can use the horizontal distance, speed, and time to calculate the time it takes for Birdman to reach the bucket:

Horizontal distance = 118m

Horizontal speed = 37m/s

Time = Distance / Speed

Time = 118m / 37m/s

Time = 3.189s

Now that we know the time it takes for Birdman to reach the bucket horizontally, we can use the vertical component of motion to calculate the height at which he needs to fly.

We know that the only force acting on Birdman is gravity, and we can use the equation of motion for a vertically launched projectile to calculate the height:

Vertical distance = (Initial vertical velocity x Time) + (0.5 x Acceleration x Time^2)

Assuming that Birdman launches himself vertically with zero initial velocity, the equation simplifies to:

Vertical distance = 0.5 x Acceleration x Time^2

Where Acceleration is the acceleration due to gravity, which is approximately 9.81m/s^2.

Vertical distance = 0.5 x 9.81m/s^2 x (3.189s)^2

Vertical distance = 49.05m

Therefore, Birdman needs to fly at a height of 49.05m to hit the bucket placed 118m away from the start of the field, assuming he flies at a speed of 37m/s.

Answers

The coolant water used for nuclear fission reactions is: crucial in the process of generating electricity.

This water serves multiple functions, such as absorbing heat generated during the fission process, moderating the neutrons, and maintaining the temperature within a safe range. By circulating around the reactor core, the coolant water collects the heat produced and transfers it to a heat exchanger, which converts it into steam. The steam then drives a turbine connected to a generator, ultimately producing electricity.

Overall, the coolant water plays an essential role in the safe and efficient operation of nuclear power plants, ensuring the continuous generation of electricity through nuclear fission reactions.

Two students are given cubic boxes, measuring 10 cm on a side. robert puts a single glass marble with a diameter of 10 cm in the box. susan puts 1,000 1-cm glass marbles in her box. which box is heavier?

Answers

The total mass of the glass marbles is m = ρV = 2500 kg/m³ × 4.19×[tex]10^{-3}[/tex] m³ = 10.5 g. Susan's box is heavier than Robert's box because it contains more glass mass.

Assuming the density of the glass marbles is constant, the weight of each box will depend on the total mass of glass in the box.

The volume of the single glass marble is (4/3)πr³ = (4/3)π(0.05m)³ = 5.24×[tex]10^{-5}[/tex] m³. The volume of the box is 10 cm × 10 cm × 10 cm = [tex]10^{-3}[/tex] m³.

Therefore, only one glass marble can fit in the box, which has a total mass of m = ρV = 2500 kg/m³ × 5.24×[tex]10^{-5}[/tex] m³ = 0.13 g.

The volume of 1,000 glass marbles is 1000 × (4/3)π(0.01m)³ = 4.19×[tex]10^{-3}[/tex] m³. Therefore, the total mass of the glass marbles is m = ρV = 2500 kg/m³ × 4.19×[tex]10^{-3}[/tex] m³ = 10.5 g.

Thus, Susan's box is heavier than Robert's box because it contains more glass mass.

If I weigh 742. 32 N on Earth at a place where g = 9. 80 m/s2 and 5900. 91 N on the surface of another planet, what is the acceleration due to gravity on that planet?

Answers

The acceleration due to gravity on the surface of the other planet is approximately 77.98 m/s².

To find the acceleration due to gravity on another planet, we can use the formula:

Weight = Mass × Acceleration due to gravity

On Earth, your weight is given as 742.32 N, and the acceleration due to gravity is 9.80 m/s².

We can rearrange the formula to solve for mass:

Mass = Weight / Acceleration due to gravity

So, on Earth, your mass would be:

Mass on Earth = 742.32 N / 9.80 m/s²

Mass on Earth = 75.63 kg

Now, let's consider the surface of another planet where your weight is given as 5900.91 N.

We'll use the same formula and solve for the acceleration due to gravity on that planet:

5900.91 N = Mass × Acceleration due to gravity on the other planet

Substituting the value of mass we calculated earlier:

5900.91 N = 75.63 kg × Acceleration due to gravity on the other planet

Now, we can solve for the acceleration due to gravity on the other planet:

Acceleration due to gravity on the other planet = 5900.91 N / 75.63 kg

Acceleration due to gravity on the other planet ≈ 77.98 m/s²

Answers

A woman lifts up a laundry basket 1.5m and carries it 20m across the room in 15s.

Work is done on the laundry basket both in lifting the basket and in walking across the room during the entire 15s.

Lifting the basket:

The work done in lifting the basket is equal to the force applied multiplied by the distance lifted. The force applied is the weight of the basket, which is equal to the mass of the basket multiplied by the acceleration due to gravity (9.8 m/s^2).

Let's assume the mass of the basket is 'm'. The work done in lifting the basket vertically is given by:

Work_lift = force_lift × distance_lift = (m × 9.8) × 1.5

Carrying the basket horizontally:

When the woman carries the basket across the room, work is done against the force of friction between the basket and the floor. The work done is equal to the force of friction multiplied by the distance traveled horizontally.

The force of friction can be calculated using the coefficient of friction (μ) and the normal force (N). The normal force is equal to the weight of the basket since it is on a horizontal surface.

Let's assume the coefficient of friction between the basket and the floor is 'μ'. The work done in moving the basket horizontally is given by:

Work_horizontal = force_friction × distance_horizontal = (μ × m × 9.8) × 20

The total work done on the basket during the entire 15s is the sum of the work done in lifting and the work done horizontally:

Total work = Work_lift + Work_horizontal
