The radiation pressure at earth’s surface is 6 mpa. consider a space ship with a surface area of 100 100 m2 and mass of 104 kg. if released with an initial velocity of 0, what is the speed with which the ship could reach the orbit of mars? assume the pressure does not change. also ignore angular momentum. the radius of earth’s orbit is 1.5 1011m while mars’ orbit radius is 2.3 1011 m.

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.
