The particle starts from rest at t=0. what is the magnitude p of the momentum of the particle at time t? assume that t> 0.

U want models on the lots. I will anticipate that's µg. However truely the models cancel out, so so long as they're consistant, that is ok. Exchange in momentum is 1µg x 5e7 + 1µg x zero.9 x 5e7 ∆P = 1µg x 5e7(1+zero.9) = 50(1.9) gm/s imparted to the gold, that is ∆P = 50(1.9) = 197µg x V V = 482000 m/s .

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d
