If the strength of the magnetic field at b is 20 units, the strength of the magnetic field at a is 80 units 20 units 40 units 5 units

answer; how far out of place which the object finished relative to the starting location;

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.
