The diagram below shows a spring compressed by a force of 6.0 Newtons from its rest position to its compressed position. Calculate the spring constant for this spring. Show all calculations, including equations [1 point], substitutions with units [1 point] and the final answer with unit [1 point].

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
