PLEASE HELP DUE IN 5 MINUTES The acceleration due to gravity g at a distance r from the center of a planet of mass Mis 9 m/s2. In terms of the orbital distance r, what
would the speed of this satellite have to be to remain in a circular orbit around this planet at this distance?
Ov=3/5
v=3r
v=6r

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
