Acar starts at a position of 2 km and moves to a final position of 4 km. what is the displacement of the car a) 0 km b) 4 km c) -2 km d) -6 km e) 2 km

the maxium height is 34m/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.
