Which statement best describes light, whether polarized or unpolarized?
a. light in which the electric and magnetic vectors oscillate parallel to the direction of propagation of the wave
b. light in which the electric vector oscillates parallel and magnetic vector oscillates perpendicular to the direction of propagation of the wave
c. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave
d. light in which the electric vector oscillates perpendicular and magnetic vector oscillates parallel to the direction of propagation of the wave

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
