Consider the complementary-bjt class b output stage and neglect the effects of finite vbe and vcesat . for ±10-v power supplies and an 8- load resistance, what is the maximum sine-wave output power available? what supply power corresponds? what is the power-conversion efficiency?
for output signals of half this amplitude,
find the output power, the supply power, and the power-conversion efficiency.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
