The force acting between two charged particles a and b is 5.2 x 10^-5 newtons. charges a and b are 2.4 x 10^-2 apart. if the charge on particle a is 7.2 x 10^-8 coulombs, what is the charge of particle b?

What sort of waves exhibit the doppler effect?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
