Design the circuit of fig. 9.14 to provide a differen- tial output voltage (i. e., one taken between the two collectors) of 1 v when the differential input signal is 10 mv. a current source of 1 ma and a positive supply of +5 v are available. what is the largest possible input common-mode voltage for which operation is as required? assume α 1.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
