Please answer my last questio If you don't find it its

You can see the transfer of mechanical kinetic energy when one pendulum hits another. Energy also seems to be lost gradually from the system as the pendulums lose speed and height with each swing. The final state of the pendulums has less gravitational potential energy than the initial state, because the pendulums come to rest at the lowest point in each of their paths. The law of conservation of energy says that energy cannot be created or destroyed, so the “lost” energy must transfer somewhere else or be changed in some way.

Think about collisions and what you know about different forms of energy. What other forms of energy might result from collisions in a Newton’s cradle?

A. chemical energy

B. electrical energy

C. electromagnetic energy

D. sound energy
