The hubble space telescope orbits earth and sends images of distant objects. why does hubble form better images than the optical telescopes used on land?

it’s larger than land-based telescopes.
it uses more powerful lenses than telescopes on land.
it orbits beyond earth’s atmosphere to avoid scattering of light.
it revolves around the outer edge of earth

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?
