Assume a satellite shines an unpolarized light on a telescope. the intensity of the light as it reaches the telescope is 1.1*10-10 w/m2 a lit, 1000-watt light bulb mounted on it. the unpolarized light from the light bulb, upon reaching the telescope, is passed through two polarizing filters that are at an angle of 30° with respect to each other, and then the resulting light is projected onto a ccd camera. what is the intensity of the light detected by the camera?

trig 15.3 cos

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
