two identical objects go around circles of identical diameter, but one object goes around the circle twice as fast as the other. the centripetal force required to keep the faster object on the circular path is

the answer would be 32*f

no. dot product   =0 when vecs at right angles

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.
