White marble is a white surface
Answer:
0 Joules
Explanation:
The work done is given by

where,
F = Force applied
s = Displacement of the object = 0 m
= Angle between the force applied and the horizontal = 0

Work is only observed when there is a displacement.
The work done by me is 0 Joules as I was unable to move it.
Answer:
If you pull a permanent magnet rapidly away from a tank circuit, what is likely to happen in that circuit?
Charge will oscillate in the tank's capacitor and inductor.
Explanation:
Answer:

Explanation:
<u>Uniform Acceleration
</u>
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:

Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
It's known a train moves from rest (vo=0) to a speed of vf=25 m/s in t=30 seconds. It's required to calculate the acceleration.
Solving for a:

Substituting:
