Two parallel rectangles having emissivities of 0.6 and 0.9 are each 1.2 meters wide and 2.4
meters high. They are positioned 0.6 meters apart. The plate with ? = 0.6 is at 1000 K while the other is
420 K. The surroundings are at 290 K and may be assumed to absorb all energy that escapes the two plates.
(a) What is the total energy lost (Watts) from the hotter plate (radiosity)?
(b) What is the radiant energy exchange (Watts) between the two plates?

A closed rectangular tank 1.2 m high, 2.4 m long and 1.5 m wide is two-thirds full of gasoline (specic gravity 0.8). Calculate the acceleration which may be imparted to the tank so that the bottom front end of the tank is just exposed. Also calculate the total forces on each end of the tank and show that the dierence between these forces equals the unbalanced force necessary to accelerate the liquid mass in the tank.

Two wires, each having a weight per unit length of 1.1x10-4 N/m, are parallel with one directly above the other.

1. Two wires, each having a weight per unit length of 1.1x10-4 N/m, are parallel with one directly above the other. The wires carry currents of 13.93 A that are equal in magnitude and opposite in direction. How far apart should the wires be placed such that the top wire will levitate above the bottom wire? Report your answer in meters. 2. Consider a -17.7 nC charge traveling next to a current-carrying wire as shown in the figure. What...
