Use the diagram to answer the question. Which statement would best describe the diagram? A. The forces acting on the car are equal in magnitude and the car will not move.

B. The applied forces of 800 N and 400 N will result the car moving to the right

C. The forces of 800 N and 400 N should be multipled to get the net force being applied to the car.

D. The magnitude of the forces acting on the car are the same but the directions are opposite.

f is prop to m1xm2 double m1 double force

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
