Answer:
Explanation:
We are given that
Radius,r=2 m
Moment of inertia,I=250
Angular velocity,
Mass of child,m=20 kg
We have to find the new moment of inertia of the merry go round.
New moment of inertia ,
Using the formula
Hence, the new moment of inertia of the merry -go-round=
Answer:
kinetic energy
Explanation:
because it is at the top going down
May be a I don’t know sorry
Answer : The correct option is, (C) cannot be reversed
Explanation :
The thermodynamic process is a process in which the thermal or heat energy is converted into mechanical energy and some amount of energy goes into surroundings. That means, the total amount of energy is not converted into mechanical energy.
Or we can say that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
The thermodynamic process is not a reversible process that means it is an irreversible process.
Hence, the correct option is, (C) cannot be reversed
