Derive the version of maxwell's equations applicable to the electric and magnetic fields in an ohmic conductor ( = oe, p = 0). show that a solution of these equations consists of a travelling wave part, multiplied by an exponential attenuation with depth into the conductor.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

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.
