Use Liebmann’s method (Gauss-Seidel) to solve for the
temperature of the heated plate in the figure. Employ
overrelaxation with a value of 1.5 for the weighting factor and
iterate to εs = 10%. Then find
the rate of heat flux (q) across the plate’s surface at the points
shown. Assume that the plate is 40 Χ 40 cm and K=
0.5 cal/(s. cm . ºC)

QUESTION 8 The following two questions refer to this problem: A parallel plate capacitor made from two circular plates with a radius of 12 cm is being charged. A circular loop with a radius of 15 cm centered on the central of axis of the plates has a displacement current of 1.5 A through the loop. What is the time rate of change of the electric field between the plates? Your answer should be in units of (V/m)/s, and you...

5 points Consider a flat metal plate of negligible thickness and area of each face A = 0.5 m2, and mass m = 10.0 kg The plate is placed on a large flat sheet of ice, such as a frozen lake surface. Due to the weight of the plate, some of the ice under the plate melts to form a layer of water of thickness h=5.0e-4 m. At time t = Os (ie. initial time), a constant force horizontal F...
