1. Which answer best explains microgravity. Astronauts are able to float because they are out far enough from the Earth to escape gravity.
Things orbiting Earth appear weightless but are actually falling around the Earth.
Gravity in space, or microgravity, is a tiny fraction of what it is on Earth.
Because gravity diminishes by the Inverse square of the distance if you get away from the earth microgra

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.
