Asinusoidal voltage δν= 37.5 sin( 100t), where δν is in volts and t is in seconds, is applied to a series rlc circuit with l-140 mh, c 99.0 μf. and r 63.0 ω. (a) what is the impedance (in ω) of the circuit? 107 (b) what is the maximum current (in a)? 350 determine the numerical value for ω (in rad/s) in the equation i-imax sin(at- 100 determine the numerical value for φ (in rad) in the equation i-imax sin(wt-d) (c) rad/s (d) 944 rad (e) what if? for what value of the inductance (in h) in the circuit would the current lag the voltage by the same angle ф as that found in part (d)? (f) what would be the maximum current (in a) in the circuit in this case?

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.

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
