A. 10 V
B. -10 V
C. 20 V
D. -20 V

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
