We levitate a negatively charged oil droplet between two charged plates. If the weight of a charged sphere (e-) of mass 1.1 x 10-14 kg is balanced by an electric field of 1.68 x 105 N/C , how many excess electrons are on the sphere.

Select the word from the list that best fits the definition classification of most stars on the h-r diagram

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?
