P4 Within one second 5.102 nitrogen mo-
lecules bounce into a plane wall of area 8 cm.
The collision is elastic.The average value of
the velocity component of the molecules per-
pendicular to the wall is 300 m/s.
a)What is the pressure exerted on the
wall?
b)Estimate the temperature of the gas and
the average kinetic energy per molecule.(Use
the assumption:<luzl>v>.)
c)Estimate the average distance among
the molecules.

In a period of 5.00 s, 5.00 x 1023 nitrogen molecules strike a wall of area 6.40 cm2. Assume the molecules move with a speed of 400 m/s and strike the wall head-on in elastic collisions. What is the pressure exerted on the wall? Note: The mass of one N molecule is 4.65 x 10-26 kg. X Calculate the momentum change in each second and use the impulse-momentum theorem to relate the momentum change to the average force between the...

Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
