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.
We eat plants that use the energy from the sun to make food
There are a lot of things about this whole statement that bother me,
but I'm pretty sure you're not interested in those. You just want a word
to glue onto the end and complete the statement. OK. Use "inertia".
