Newton's first law of motion states that an object that is resting (not moving) will stay motionless unless an external force acts on it and an object in motion will stay in motion unless an outside force acts on it. This law is known as newton's law of inertia.

Answer:
A. he can hear music coming from the radio.
Explanation:
Jeff knows that the radio produces sound energy because he can hear music coming from the radio.
The music from the radio is a form of sound energy.
- Sound energy is a form of energy dissipated from a body and can be discerned by humans.
- Sound is a mechanical wave that requires a material medium for its propagation.
- It travels by series of rarefaction and compression along its path of motion.
- Since sound energy is an energy in motion, it is a kinetic energy.
- It travels parallel to its source and therefore, it is a longitudinal wave.
