The true statements about generators would be :
They convert motion energy to electric energy
They use the relative motion of a magnet and a coil of wire.
Explanation:
Generators use the energy of the rotating coil in relative motion with magnets to induce a current within the wire. Generators are devices that convert energy into a voltage by the relative motion of the magnet and a coil that changes flux.
The sum of balanced forces will always be equal to zero.
Answer : The correct option is, 2880 J
Solution :
According to the question,
K.E + Energy lose to friction = P.E
where,
m = mass of object = 60 Kg
g = acceleration due to gravity =
h = height = 10 m
v = velocity of an object = 10 m/s
Now put all the given values in the above formula, we get the energy lost to friction.
Therefore, the amount of energy she lose to friction is, 2880 J
