The mathematical expression for the change in free energy of a system is δg =δh - tδs. which of the following is correct? the mathematical expression for the change in free energy of a system is δg =δh - tδs. which of the following is correct? t is the temperature in degrees celsius. δh is the change in entropy, the energy available to do work. δs is the change in enthalpy, a measure of randomness. δg is the change in free energy.

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.

How are the crust and the inner core alike? a) they are both solid. b) they both have the same temperature. c) they are both under the same pressure. d) they are both very close to the center of the earth.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
