A gas undergoes isochoric heating, during which it gains 5470 J of heat and attains a pressure of 3.45 X 105 Pa. Following this, it experiences an isobaric compression that is also adiabatic, in which its volume decreases by 6.84 X 10-3 m3. Find the total change in the internal energy of the gas for this two-step process. Be sure to include the algebraic sign ( or -) of the total change in the internal energy.

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
