Without looking at the choices I would have said heavy but since that is not on here I would say large.

Explanation:

When the water droplets in the clouds combine them because heavy and form into raindrops.

i really wish i could answer this question for you

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
