You know that gravity changes the potential energy of falling objects into kinetic energy. Design an experiment
to investigate how distance from the ground will affect a
ball’s potential energy. Write out the materials you need
and the steps you will follow. Record your results and
observations.

They are all solids.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
