Consider the coin diagram. We see that for the ‘four heads’ state, there are w = 1 microstates. For this question, we will call ‘two heads, two tails’ state 1, and ‘one head, three tails’ state 2. a) For state 1, find w.
b) What is the entropy of the system for state 1?
c) What is the entropy of the system for state 2?
d) Imagine now that we throw the coins and they land in state 1. We then rearrange them into state 2.
i. What is the change in entropy here?
ii. Which law does this violate?
iii. What went wrong? What must we also consider?

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

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.
