Which of the following is an example of chemistry research in the main area of energy? . a. producing bioplastics. b. specific reactions between prescription drugs and chemicals in cells. c. developing rechargeable batteries. d. determining the composition of extra-terrestrial soil and rocks.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
