1. In a circuit 20mC of charge flows for 5 minutes, find the current in the circuit. 2. The voltage supplied by a battery is 5V, the total charge flowing in the circuit is 10mC. What is the energy supplied by the battery?

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
