Four wires are made of the same highly resistive material, cut to the same length, and connected in series. wire 1 has resistance r1 and cross-sectional area a. wire 2 has resistance r2 and cross-sectional area 2a. wire 3 has resistance r3 and cross-sectional area 3a. wire 4 has resistance r4 and cross-sectional area 4a. a voltage v0 is applied across the series, as shown in the figure. find the voltage v2 across wire 2.give your answer in terms of v0, the voltage of the battery.

Sarah and michelle work at a tech company that designs exercise apps. sarah tells michelle she has heard that james, their supervisor, interviewed with a competitor and may be leaving the company, which would open up a management position. what kind of power is sarah exerting?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
