Given the density operator 4 construct the density matrix. show that this is the density operator for a mixed state. determine ( ( and (s.) for this state.

Are formed where bumps from two surfaces come into contact ?

What happens when the vapor pressure of a liquid is equal to the external pressure?

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n.m2 . find the energy u1 of the dielectric-filled capacitor.
