A long, hollow, cylindrical conductor (with inner radius 2.0 mm and outer radius 4.0 mm) carries a current of 24 A distributed u
tigry1 [53]

Answer:

a) 0.0048 T

b) 0.00093 T

c) 0 T

Explanation:

B = μ(0) [I - i'] / 2πr

where I = 24, and i' = 0, this means that

B = [12.568*10^-7 (24 - 0) ] / 2 * 3.142 * 0.001

B = 3.016*10^-5 / 0.006284

B = 0.0048 T

b), formula is the same, except for change in values, so we have

I = 24, and

i' = (3y2 - 2y2) / (4y2 - 2y2) * 24

i' = 10, and substituting these in the equation, we have

B = [12.568*10^-7 (24 - 10) ] / 2 * 3.142 * 0.003

B = (12.568*10^-7 * 14) / 0.018852

B = 1.76*10^-5 / 0.018852

B = 0.00093 T

and for the last one, we have

I = 24 and i' = 24 also, so that

B = [12.568*10^-7 (24 - 24) ] / 2 * 3.142 * 0.005

B = 0 / 0.03142

B = 0

A car travels 2,000 mi at a<br> constant speed of 70 mi/hr.<br> How long did the trip take?
ella [17]

Answer:

<h2>28.57 hours</h2>

Explanation:

The time taken can be found by using the formula

t =  \frac{d}{v}  \\

d is the distance

v is the velocity

From the question we have

t =  \frac{2000}{70}  =  \frac{200}{7}  \\  = 28.571428 ...

We have the final answer as

<h3>28.57 hours</h3>

Hope this helps you

pogonyaev
1. The signs of the velocities of the balls were changed, this is a result of the elastic collision between the two balls. The law involved in here is the Law of Interaction.
2. During the elastic collision, the momentum is conserved. 
3. The velocity would be lower. There is a tendency for these balls to stick together.
