A point charge with charge q_1 = 2.70 micro C is held stationary at the origin. A second point charge with charge q_2 = -5.00 micro C moves from the point ( 0.170 m, 0) to the point ( 0.240 m, 0.265 m). How much work W is done by the electric force on the moving point charge?

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.
