The center of a large bar magnet is z = 25 cm from a thin plate of high resistance material 12 cm long, 2.5cm high, and 0.1 cm thick that is connected to a 240 V power supply whose internal resistance is negligible. The bar magnet is perpendicular to the plate. The mobility of charge canners in the thin plate is 3.8 x 10^(-4) (m/s)/(V/m), and the number density of singly charged charge carriers is 3.6 x 10^23 m^(-3). A voltmeter connected precisely vertically across the A thin plate and reads +1.2 x 10^(-5) V. A low-resistance ammeter is in series with the rest of the circuit.
(a) Are the charge carriers electrons or holes?
(b) What is the magnetic deplete moment of the maggots? Include unit. (Enter the magnitude.)
(c) What does the ammeter read, including sign?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
