place the charge q= 2.10-5C at the origin O of the Oxy-axis system. consider two points A(6;0) and B(3;4) on the axes with unit of measurement in cm. choose the potential origin at infinity. Calculate the work done by the electric field when moving the charge q=-1uc from A to B

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Which of the following are appropriate acceleration units?

Which of these activities increases the amount of carbon in the atmosphere?
