Design a two-stage band-pass filter using two 1Ω resistors and two 1 capacitors (i. e. a circuit where the transfer function drops to zero at low and high frequencies and passes a range of frequencies in-between)

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.

The heliocentric and the geocentric models of the solar system included these central principles
