Jack and Jill sit next to each other in class. She has a mass of 45.0 kg and his mass is 60.0 kg. a) If they are 0.250 meters apart, what is the gravitational force between Jack and Jill? Show the equation you used to calculate an answer. (4 Points)

b) Explain what would happen to the gravitational force (FG) if the distance between

Jack and Jill was tripled while their masses remained the same. (2 Points)

50 inches should be the resultant vector

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

i believe the answer is electric potential.
