A10v ac sine wave at 60hz, is rectified by a half-wave rectifier, put across a large capacitor, fed to a 5v regulatorand then to a load which draws 100ma. assume a) the regulator draws no current other than that sent to the load (it is a type known as a switching regulator, unlike the diode regulators we have been studying) b) the input voltage of the regulator can be as low as 5v estimate how big the bfc has to be, in mf.

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?
