Two particles move about each other in circular orbits under the influence of gravitational forces, with a period τ. their motion is suddenly stopped at a given instant of time, and they are then released and allowed to fall into each other. prove that they collide after a time τ/(4 2).

carla slowed down in the beginning of her trip, stopped, and then sped up

c)as speed changes, wavelength and frequency change.

everything changes!

are there options? cause you ain’t. real specific

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
