On which of these hills does the ball roll down with increasing speed and decreasing acceleration along the path? (Use this example if you wish to explain
to someone the difference between speed and acceleration.)

i already answered it by 34/s

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
