Jupiter's satellite europa orbits jupiter with a period of 3.55 d at an orbital radius of 6.71 108 m (assume the orbit to be circular). g = 6.67 x 10-11 nm2 /kg2 (a) determine the mass of jupiter from the data given. (b) what is the orbital velocity of europa? (c) what is the gravitational field’s magnitude at europa?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
