The question is incomplete. Here is the complete question.

Lightning bolts can carry currents up to approximately 20kA. We can model such a current as the equivalent of a very long, straight wire.

(a) If you were unfortunate enough to be 5.5m away from such a lightning bolt, how large a magnetic field would you experience?

(b) How does this field compare to one you would experience by being 5.5cm from a long, straight household current of 5A?

Answer: (a) B = 7.27 x 10⁻⁴ T

              (b) Approximately 40 times higher than a household one.

Explanation: Using Biot-Savart Law, the magnetic field in a straight, long wire is given by

[tex]B=\frac{\mu_{0}I}{2.\pi.r}[/tex]

where:

[tex]\mu_{0}[/tex] (permeability of free space) = [tex]4.\pi.10^{-7}[/tex]T.m/A

(a) If lightning bolt is compared to a long and straight wire, then magnetic field is

[tex]B=\frac{4.\pi.10^{-7}.10.10^{3}}{2.\pi.5.5}[/tex]

B = 7.27 x 10⁻⁴ T

The magnitude of magnetic field in a lightning bolt is 7.27 x 10⁻⁴ T

(b) Magnetic field in a household wire will be

[tex]B=\frac{4.\pi.10^{-7}.5}{2.\pi.5.5.10^{-2}}[/tex]

B = 1.82 x 10⁻⁵ T

Comparing fields:

[tex]\frac{7.27.10^{-4}}{1.82.10^{-5}}[/tex] ≈ 40

The filed for a lightning bolt is approximately 40 times higher than for a household wire.

Answer : The volume of water in graduated cylinder is 15.5 mL.

Explanation :

As we know that for the measurement of the volume of liquid in graduated cylinder are shown by placing the graduated cylinder on the flat surface and then view the height of the liquid in the graduated cylinder with the naked eyes directly level with the liquid.

The liquid will tend to curve downward that means this curve is known as the meniscus.

In the case of colored liquid, we are always read the upper meniscus of the liquid for the measurement.

In the case of colorless liquid, we are always read the lower meniscus of the liquid for the measurement.

In the given image, there are 5 larger and 5 smaller division between the 15 and 20 and the solution is colored. The value of larger division is 1 mL and smaller division is 0.5 mL.

So, we will read the upper meniscus of the liquid for the measurement.

Hence, the volume of water in graduated cylinder is 15.5 mL.

Answer:

Teeth

Explanation:

The main parts of geards are the base and the teeth.  When two wheels are combined and joined by a belt, the larger wheel will rotate more slowly than the smaller wheel, but it will rotate with a greater force. A big wheel with twice the circumference of a small wheel will rotate with twice the force and half the speed of the small wheel.

Gears are connected together in various ways to transmit motion and force. Two connected gears of different sizes will cause one of the gears to turn faster or slower than the other. One gear will also move the force in a different direction than the other.

Gear ratio is the number of teeth on the following gear divided by the number of teeth on the driving gear (the gear inputting the motion).

A low gear ratio = more speed = less force

A high gear ratio = less speed = more force

Pull towards itself.

Explanation:

That's what I know.

Tension is a force that tends to pull or stretch an object. A flexible material, like a rope, cable, or string, is used to transmit the force.

A force known as tension has a tendency to pull or stretch an object. When a flexible medium, like a rope, cable, or string, is under strain and supporting an imposed load or weight, it transmits force via the flexible medium.

A rope or cable that is under tension receives equal and opposing forces pulling it in different directions at either end. For instance, the tension in a rope will be the same along its whole length if both ends are pulled with equal effort.

When you use a pulley system to hoist a weight, suspend an object from a rope, or support the weight of traffic on a bridge, tension can be present.

Therefore, Tension is a force that tends to pull or stretch an object.

Answer:

Average speed is  6m/s

Average velocity is 5.859m/s

Explanation:

Average speed, s = d/t

d is distant

t is time

speed north is 800m and 110s

speed due south is 400m and 90s  

Average speed = (800+400) / (110+90)

                          = 1200/200

                          =6m/s

Average velocity V = (v + u)/2

v = final velocity

u = initial velocity

V = (7.273 + 4.444)/2 = 11.717/2

V = 5.859m/s

(a) The angle of refraction for the ray inside the glass will be 19.26°.

(b)  It  is proved that the rays in the air on either side of the glass are parallel to each other

When a ray of light passes through a different medium some part of the light gets reflected and some part gets refracted by changing its angle in the different medium this angle is called the angle of refraction and the phenomenon is called refraction of light.

It is given that,

The angle of incidence = 30.0°

Index of reflection of glass = 1.52

(a) For finding the angle of the refraction for the ray inside the glass we will use Snell's Law

[tex]\dfrac{Sini}{Sinr} =\mu[/tex]

Put the value into the formula

[tex]Sinr=\dfrac{Sini}{\mu} =\dfrac{Sin30}{1.52}[/tex]

[tex]r=Sin^{-1}(0.329)[/tex]

[tex]r=19.26^o[/tex]

(b) Now for proof of  [tex]Sin\ i =Sin\ e[/tex]

The incident ray and emerging ray are equal then the ray will be parallel.

We need to prove that the rays in the air on either side of the glass are parallel to each other.

Using the formula for emerging ray

[tex]\dfrac{Sin\ e}{Sin\ r} = \mu[/tex]

[tex]Sin\ e=\mu Sin \ r=1.52\times Sin19.26[/tex]

By putting the values in the formula

[tex]e=Sin^{-1}(1.52\times0.3289)[/tex]

[tex]e=30^o[/tex]

Since the incident angle and the emerging angle are equal

[tex]Sin \ i=Sin \ e[/tex]

Thus incident and emerging rays) are parallel to each other.

(a) So the angle of refraction for the ray inside the glass will be 19.26°.

(b)  It  is proved that the rays in the air on either side of the glass are parallel to each other

your welcome and please answer my question its called part 1 math work if you could do that i will give you 40 points

Answer:

We are given:

m1 = 500 kg             m2 = 1500 kg

v1(initial) = x m/s       v2(initial) = 0 m/s

v1(final) = 20 m/s      v2(final) = 20m/s

According the the law of conservation of momentum:

m1v1(initial) + m2v2(initial) = m1v1(final) + m2v2(final)

Plugging the values in this formula:

(500*x) + (1500 * 0) = (500 * 20) + (1500 * 20)

500x = 20(1500 + 500)

500x = 20(2000)

x = 20 * 4

x = 80 m/s

Therefore, the car was initially moving at a velocity of 80 m/s

Answer:

Third Option: It is decreasing by 10m/s^2

Explanation:

When a ball is thrown in the air, it's fastest velocity occurs just as it leaves its source (e.g. the hand that throws it), and just before it hits the starting point. This is because this is when it has the most kinetic energy which translated into speed. As it rises, it starts to lose kinetic energy as it transforms into gravitational potential energy as the ball is fighting against the force of gravity as it moves further away from the Earth's surface. This means it begins to slow down until its speed is 0, its highest point, before falling and gaining kinetic energy again. Because of this, we can eliminate options 1, 2 and 5 as we know the ball's velocity decreases as it rises.

As the ball rises it's velocity decreases at a constant rate, as the amount of kinetic energy it has is proportional to its height. Therefore, the best option is option 3, as it states it is decreasing and gives a constant deceleration rate.

Substance X transfers thermal energy to substance Y through conduction. What is an accurate conclusion about the condition of both substances before conduction occurred? Substance X's molecules were faster than substance Y's.

Explanation:

An accurate conclusion about the condition of both substances before conduction occurred is substance X’s molecules were faster than substance Y’s.

Thermal energy is the energy released in the form of heat. It manifests itself by releasing heat. It results from the atoms' movement or vibration, so it displays the system's internal energy. We define thermal energy as part of the internal energy of a system.

It is an extensive quantity, it depends on the size of the system, or on the amount of substance it contains. The SI unit of thermal energy is the joule (J). It is the energy contained within the system, excluding the kinetic energy of motion of the system as a whole and the potential energy of the system. Thermal energy is often classified into various types on the basis of how this internal energy, in the form of heat, is transferred from one body to another.

The correct answer is option C.

Answer:

A.) 22.12 m/s

B.) 3.27 m

C.) 0.57

Explanation:

Given that a mass of 0.4 kg is dropped from rest in a medium offering a resistance of 0.2|v|, where is measured in meters per second. Acceleration due to gravity is 9.8 m/s^2.

a. If the mass is dropped from a height of 25 m, its initial velocity U will be equal to zero. when it hits the ground, the final velocity V will be:

V^2 = U^2 + 2gH

Substitute g and the height into the formula

V^2 = 2 × 9.8 × 25

V^2 = 490

V = 22.12 m/s

b. If the mass is to attain a velocity of no more than 8 m/s, the maximum height from which it can be dropped will be calculated by using the same formula.

V^2 = U^2 + 2gH

Where V = 8 m/s and U = 0

8^2 = 0 + 2 × 9.8 × H

64 = 19.6H

H = 64/19.6

H = 3.27 m

c. Suppose that the resistive force is k|v|, where v is measured in m/s, and k is constant. If the mass is dropped from a height of 25 m and must hit the ground with a velocity of no more than 8 m/s, determine the coefficient of resistance that is required.

The energy at 25m heigh will be:

E = mgh

E = 0.4 × 9.8 × 25

E = 98 J

1/2mv^2 = 98

1/2 × 0.4 × ( 8 - v )^2 = 98

0.2( 8 - v )^2 = 98

( 8-v)^2 = 98/0.2

( 8 - v )^2 = 490

8 - v = 22.12

v = 22.14 - 8

v = 14.14

Coefficient of resistance required will be 8/ 14.14 = 0.57
