1b. a heat storage arrangement is designed to store 4.2 x 10 joules of heat. The material is heated from 25°c to 45°c but melts at 32°c. the specific heat
capacity of solid is 2.0 kgkgk the specific heat of the liquid is 4.0 kgkgk
and its specific latent heat of fusion (mass) is required?​

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
