Answer:
80×5×10=4000J
so therefore, work done on the body is 4000J
Answer:
yes friction is needed hope this helps might of been to long tho
Answer:
The self-induced emf in this inductor is 4.68 mV.
Explanation:
The emf in the inductor is given by:

Where:
dI/dt: is the decreasing current's rate change = -18.0 mA/s (the minus sign is because the current is decreasing)
L: is the inductance = 0.260 H
So, the emf is:

Therefore, the self-induced emf in this inductor is 4.68 mV.
I hope it helps you!
Answer:
Yes, yes it would since we need light
