Asquare loop of side length a =2.9 cm is placed a distance b = 1.2 cm from a long wire carrying a current that varies with time at a constant rate, i. e. i(t) = qt, where q = 2.3 a/s is a constant. show answer correct answer 25% part (a) find an expression for the magnetic field due to the wire as a function of time t at a distance r from the wire, in terms of a, b, q, t, r, and fundamental constants. b(t) = ( μ0 q t )/( 2 π r ) part (b) what is the magnitude of the flux through the loop? select the correct expression. part (c) if the loop has a resistance of 2.5 ω, how much induced current flows in the loop?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

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.
