Answer:
Energy, E = 178.36 J
Explanation:
It is given that,
Mass 1,
Mass 2,
Mass 3,
Height from which they are dropped, h = 1.3 m
Let m is the energy used by the clock in a week. The energy is equal to the gravitational potential energy. It is given by :
E = 178.36 J
So, the energy used by the clock in a week is 178.36 Joules. Hence, this is the required solution.
