Why does the water in a swimming pool stay cool on a hot, sunny day? because radiation has no effect on water
because of convection
because the pool is a good insulator
because the Sun's rays are reflected off of the pool's surface

this one:

as we gain mass the force of gravity on us increases.

pls mark me as the ! : d

0.19 m/s and 0.45 m/s

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
