Part Q A convex spherical mirror has radius of curvature -37.0 cm. Find the image distance if the object distance is 12.0 cm. Express your answer with the appropriate units.

For the gravitational field of a large massive object, such as the sun, what is the gravitational potential energy of a smaller mass very, very far away? O mgh O 42

A 47-kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.2 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.

Hi there, quick true or false question. If you double the mass of an object that is at some elevated position, above a reference level, youd double it's gravitational potential energy. True or False Thanks!!
