Answer:

Consider our plane flying at a speed of 80 km/hr into a 40 km/hr crosswind. Its speed, relative to the ground, can be calculated by adding the two vectors as shown on the right. What happens to the speed of the plane as the crosswind increases in magnitude? Look at the animation on the right. It is obvious that the speed of the plane, relative to the ground, increases in magnitude.

Explanation:

Answer:

60km/hr

Explanation:

R=80 - 20

=60km/hr, north

Answer:

m = 15 kg

Explanation:

Applied force to the cart, F' = 18 N

Force of friction, f = 15 N

Net force acting on the cart,

F = F' - f

F = 18 - 15

F = 3 N

The change in velocity of the cart is 1 m/s every 5 s.

We need to find the mass of the cart.

The formula of net force is given by :

F = ma, where a is the acceleration of the cart

[tex]F=\dfrac{m\Delta v}{t}\\\\m=\dfrac{Ft}{\Delta v}\\\\m=\dfrac{3\times 5}{1}\\\\m=15\ kg[/tex]

So, the cart's mass is 15 kg.

Answer:

The new volume of the [tex] NH_{3}[/tex] sample is 3.27mL.

Explanation:

Given the following data;

Original Volume, V1 = 2.50-mL

Original Temperature, T1 = 325K

New Temperature, T2 = 425K

To find new volume V2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] VT = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making V2 as the subject formula, we have;

[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]

[tex] V_{2}= \frac{2.50}{325} * 425[/tex]

[tex] V_{2}= 0.0077 * 425[/tex]

V2 = 3.27mL

Therefore, new volume of the [tex] NH_{3}[/tex] sample is 3.27mL.

Answer:

*Decreasing an object's velocity can increase kinetic energy. *Increasing an object's velocity can decrease kinetic energy. *The velocity of an object has no effect on kinetic energy.

ExplanIf the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure (Figure 1).

Answer:

there are three type of notion

Answer: Zero.

Explanation:

By the first Newton's law, we know that:

every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Now, we know that the car is moving with constant speed, then there is no net force acting on the car, which means that the car is already in equilibrium.

Then if we add one force to the situation, the car will not be anymore in equilibrium.

The correct option is zero.

Answer:

Nothing anywhere is sitting still. As all is moving.

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Tissue paper

Explanation:

Tissue paper absorb most sound waves because it is porous. Materials that absorb sound most are highly porous like tissue because that have pores and allow sound to penetrate through it channels or cavities which makes it to loss part or all of it energy. This material allow sound wave to enter through it.

Sound energy is distributed as a result of heat loss which is caused by the air molecules of the pores wall in the material.

Answer:

The answer is below

Explanation:

Acceleration is the rate of change of velocity with respect to time. The S.I unit of acceleration is m/s².

We say that there is acceleration if there is a change of distance or change in velocity (increase or decrease) or both.

The statement above is an example of acceleration because there is a change in velocity. The velocity when the motor was at rest was 0, but an increase in acceleration caused the train to move a distance of 10 meters.

THIS IS THE ANSWER

Answer: The energy to move the fluid is provided by the pressure on the fluid surface.

Explanation:  The frictional losses in the suction pipework and rises in the suction pipework system will reduce the fluid pressure at the pump inlet. If the pump inlet connection is removed the fluid will not flow out of the suction pipework. Hope this helps! :)

The distance from the school will be 229 Km

Velocity is the distance travel in a specific direction per time taken. Velocity is a vector quantity.

Given that at 1:00 p.m. a car, traveling at a constant velocity of 82 km/h toward the west, is 24 km to the west of our school. How far from the school will it be at 3:30 pm ?

The time taken by the car will be = 3:30 - 1:00 = 2:30 = 2.5 hr

Since the speed is constant, V = s/t

82 = s / 2.5

s = 82 x 2.5

s = 205 Km

The distance from the school = 24 + 205 = 229 Km

Therefore, the distance from the school will be 229 Km

Answer:

3333.33 m/s²

Explanation:

From the question given above, the following data were obtained:

Total Velocity (v) = 40 m/s

Total Time (t) = 0.012 s.

Average acceleration (a) =..?

Average acceleration can be defined as follow:

Average acceleration (a) = Total velocity (v) / total time (t)

a = v / t

With the above formula, we can obtain the average acceleration of the ball as shown below:

Total Velocity (v) = 40 m/s

Total Time (t) = 0.012 s.

Average acceleration (a) =..?

a = v / t

a = 40 / 0.012

a = 3333.33 m/s²

Therefore, the average acceleration of the ball is 3333.33 m/s².

Explanation:

Pressure Exerted by a Column of Liquid

The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:

P = ρgh

Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.

The data provided is as follows:

[tex]\rho=1000\ Kg/m^3[/tex]

[tex]g=9.8m/s^2[/tex]

[tex]h=80\ cm = 0.8\ m[/tex]

The pressure is:

[tex]P = 1000\ Kg/m^3\cdot 9.8\ m/s^2 \cdot 0.8\ m[/tex]

[tex]\boxed{P=7,840\ Pa}[/tex]

Answer:

If you go to a planet with little gravity you will be lighter and the stronger gravity is the heavier you are. The mass of any object that is experiencing different gravity forces will stay the same the only thing that will change is the weight.

The force of gravity affects weight by exerting a downward force on objects near the Earth's surface. Weight is the measure of the gravitational force acting on an object. The force of gravity is directly proportional to the mass of an object.

According to Newton's law of universal gravitation, the force of gravity between two objects is determined by their masses and the distance between them. Near the surface of the Earth, the force of gravity can be approximated using the equation:

F = mg

Where:

F is the force of gravity

m is the mass of the object

g is the acceleration due to gravity (approximately 9.8 meters per second squared on the surface of the Earth)

As you can see from the equation, weight (force of gravity) is directly proportional to the mass of an object. This means that as the mass of an object increases, its weight increases as well. For example, a heavier object will experience a greater force of gravity and, therefore, have a greater weight compared to a lighter object.

It's important to note that weight is a force, typically measured in units such as newtons or pounds, whereas mass is a measure of the amount of matter in an object, typically measured in kilograms or pounds. Weight can vary depending on the strength of the gravitational field, whereas mass remains constant regardless of the location. For example, an object that weighs 100 pounds on Earth would weigh less on the Moon due to the Moon's weaker gravitational pull. However, the mass of the object would remain the same.
