House current, which has an rms voltage of 110 v and a frequency of 60 hz, drives a resistor of a variable resistance set at r = 50ω? , a capacitor of fixed capacitancec = 20 μf, and an inductor of variable inductance, connected in series. (a) what is the power absorbed by the circuit if l = 10 mh?
(b) what would be the power drawn if the resistance were halved without changing the setting of the inductance?
(c) what is the maximum power drawn in part (b)?

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
