Investigating springs. Investigate the behaviour of a spring when it is loaded with masses. a. How does the extension change?
b. How does the time of its oscillations change?
a. How does the energy of the system change?
b. Can you find an expression for the total energy in the system at any time? P
c. lot a graph to show how each form of energy varies over the course of one complete oscillation.
d. Can you find a relationship between the energy of the system and the load on the spring?
e. Can you explain this relationship?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
