A50.0 nf air-filled parallel plate capacitor is connected in series with a 2.85 kn resistor and a battery of emf 36.0 v. (a) determine the final charge on the capacitor. (b) once the capacitor is fully charged and there is no current in the circuit, a sheet of plastic with a dielectric constant of 2.75 is introduced in the gap between the plates of the capacitor, completely filling the gap. if the area of each plate is 0.275 m² what is the electric field inside the plastic immediately after it is inserted (before there is any change in the charge on the plates of the capacitor)? n/c

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Choose the most likely outcome of this scenario: jen decided to go bike riding without a helmet. while no one is around during her ride, she is thrown from her bike when her wheel goes into a pothole. she is not injured, but she is terrified to get back on her bike. what happens next? a. her physical health is affected even though she wasn't hurt. b. her mental and emotional health are affected because she is afraid to get back on her bike. c. her social health is affected because she is worried her friends saw the fall. d. her overall health is not affected at all by her fall.
