Please help!
A planet is orbiting a nearby star in a circular, face-on (no inclination) orbit. The planet's distance from the star is 15 AU, and the star is 202 light years from Earth. b) What size telescope would be required in order to resolve the star from the planet, assuming we could work "at the diffraction limit" at a wavelength of 7 μm? Answer in metres

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5200 m/s. By observing the planet, you determine its radius to be 4.48×106m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 11.6 m/s at an angle of 30.8∘ above the horizontal. a)If resistance due to the planet's...
