Objects 1 and 2 attract each other with a gravitational force
of 36.0 units. if the mass of object 1 is doubled and the
mass of object 2 is tripled and the distance separating
objects 1 and 2 is halved, then the new gravitational force
will be units.

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?
