When you lift a book from the ground to your desk, you are doing positive work. By lifting the book, I change its energy and its original place. It gains energy. I'm not sure what kind of energy though, sorry.
Explanation:
If a metal rod of length L moves with velocity v is moving perpendicular to its length, in a magnetic field B, the induced emf is given by :
The electric field in the conductor is given by :
It is clear that the electric field is independent of the length of the rod. If the length of the rod is doubled, the electric field in the rod remains the same.
Answer:
Explanation:
GIVEN DATA:
Total mass ( rider + his tube) = 80 kg
tension Force = 360 N
height of slope = 30 m
length of slope = 120 m
we know that thermal energy is given as
E_{th} = W- Ug
W= F*d = (360N*120m)= 43200 J
Ug= m*g*h = (80kg*9.8m/s2*30m) = 23520 J
