Do the same for disc. Moment of Inertia of disc about its axis = MR²/2
All the energy that was in the first marble was transfers into the second marble
Atomic mass = protons + neutrons
So the total number of protons and neutrons
Answer : The average power delivered to the circuit is, 42.6 watt
Explanation :
The relation between power, voltage and current is:

where,
P = power of circuit = ?
I = current = 6.0 A
V = voltage = 7.1 V
Now put all the given values in the above formula, we get the average power delivered to the circuit.


Thus, the average power delivered to the circuit is, 42.6 watt
