An archer uses a bow to fire two similar arrows with the same string force. One arrow is fired at an angle of 60° with the horizontal, and the other is fired at an
angle of 45° with the horizontal. Compared to the arrow fired at 60°, the arrow fired
at 45° has a -

A) longer flight time and longer horizontal range

B) longer flight time and shorter horizontal range

C) shorter flight time and longer horizontal range

D) shorter flight time and shorter horizontal range

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?
