Calculate the electrical force between two objects with charges of 2.2 uC and 4.2 uc. respectively, placed at different distances apart. Complete the table below with your
calculations. Graph the electrical force versus the distance between the two objects. Be sure to
include your axes labels and graph title. What happens to the force when the distance is
doubled? Quadrupled?

answer; i believe that the correct answer is (d) a very small amount of mass

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

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
