Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?

Could we see a galaxy that is 20 billion light-years away?

He acceleration due to gravity on the surface of mars is about one third the acceleration due to gravity on earth’s surface. the weight of a space probe on the surface of mars is about
