A satellite orbits the earth at a height of 600,000 m above the surface of the earth. Determine the speed of the satellite.

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?

The speed of light can be used to measure the
