1. How does centripetal force due to gravity keep a satellite in orbit?

It continuously changes the direction of the satellite.

It provides the thrust to launch the satellite into space.

It prevents the satellite from falling toward Earth.

It keeps increasing the speed of the satellite.

Which object is most likely represented by a dot?

If anyone who can me with this hw? i would really appreciate it

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
