Answer:
The electric potential is 
Explanation:
From the question we are told that
The length of the rod is 
The total charge of the rod is 
The length from the center is 
The diagram illustrating the setup for this question is shown on the first uploaded image
From the diagram the potential at point A
is mathematically represented as

Where K is the coulomb constant with a value 
where q is the charge in charge the rod relative to its distance from A is mathematically represented as

This a small unit length of the rod
So 
=> ![V = k\frac{q}{L} ln [\frac{4}{2} ]](https://tex.z-dn.net/?f=V%20%3D%20%20k%5Cfrac%7Bq%7D%7BL%7D%20%20ln%20%5B%5Cfrac%7B4%7D%7B2%7D%20%5D)

Substituting values


Answer:
μs = 0.75
μk = 0.58
Explanation:
From a force diagram:
(1)
(2)
When it starts slipping, friction force is the maximum and acceleration is 0. Replacing these conditions on (1):
Solving for μs:

μs = tan 36.7° = 0.75
When it moves at constant speed, friction force is kinetic friction and acceleration is 0. With these conditions the coefficient is:
μk = tan 30.1° = 0.58
Answer:
Are you looking for the formula? because if so:
M L^2 T^-3 I^-2
Explanation:
May I have brainliest please? :)
Answer:
113 miles
Explanation:
45.00 x 2.50= 1.12.5 so 113 miles in 2.50 hours
The energy transformations that occur as you coast down long hill on a bicycle, including the brakes to make the bike stop at the bottom, is that at the top of the hill you have high GPE AND LOW KE, on your way down you have HIGH KE AND LOW GPE, and at the bottom you have thermal energy due to the stop of the brakes.
the law of conversation of energy and describe the energy transformations that occur as you coast down a long hill on a bicycle and then apply the brakes to make the bike stop at the bottom.
