Agood way to de-magnetize something is a.) run a current through it. b.) put it near a compass. c.) heat it. d.) place it in an electric field.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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.
