The hubble telescope’s orbit is 5.6 x 105 meters above earth’s surface. the telescope has a mass of 1.1 x 104 kilograms. earth exerts a gravitational force of 9.1 x 104 newtons on the telescope. what is the magnitude of earth’s gravitational field strength at this location?

Agardener uses a wheelbarrow to move soil from a truck to his garden. on the first trip from the truck to the garden, the wheelbarrow is half-full of soil and the gardener applies a certain force to cause it to accelerate. on the second trip, the wheelbarrow is full of soil. although the gardener applies the same amount of force to the wheelbarrow, he cannot move it with the same rate of acceleration. what should the gardener do to move the wheelbarrow at the same rate of acceleration for the second trip?

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
