You are working out on a rowing machine. each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.3 m in a time of 0.95 s. the readout on the display indicates that the average power you are producing is 85 w. what is the magnitude of the force that you exert on the handle

Atotal charge of –6.50 µc is uniformly distributed within a sphere that has a radius of 0.150 m. what is the magnitude and direction of the electric field at 0.300 m from the surface of the sphere? a) 2.89 × 105 n/c, radially inward b) 6.49 × 105 n/c, radially outward c) 4.69 × 105 n/c, radially inward d) 9.38 × 105 n/c, radially outward e) 1.30 × 106 n/c, radially inward

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
