Two point charges, a and b, are separated by a distance of 16.0cm. the magnitude of the charge on a is twice that of the charge on b. if each charge exerts a force of magnitude 43.0 n on the other, find the magnitudes of the charges. charge a: in c
charge b: in c

Ais not a compound machine. a. bolt b. shovel c. handcart (dolly) d. see-saw (teeter totter)

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

In science and physics what is the standard unit of measure for speed?
