c. Riding a bicycle
d. A boy catching a ball​

Answer 1

Answer:

While riding a bicycle,the muscular energy of the rider gets transferred to heat energy and kinetic energy of the bicycle.Heat energy heats the rider's body.Kinetic energy provides a velocity to the bicycle to move in rotation.The transformation can be shown as:

Muscular energy=kinetic energy+heat energy

During transformation,the total energy remains conserved
