If the astronaut in the video wanted to move upward, in which direction should he throw the object? Why?
1.He should throw the object upward because according to Newton’s third law, the object will then exert a force on him in the same direction (i. e., upward).
2.He should throw the object upward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i. e., downward).
3.He should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i. e., upward).
4.He should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the same direction (i. e., downward).

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
