Three charges are located at the vertices of a triangle, as shown. which vector best represents the net force acting on the +4 c charge in the diagram? a) w b) x c) y d) z

Why does the input force have to be greater than the force needed to lift the bale?

A150 w lamp emits light of wavelength 590 nm uniformly in all directions. what is the photon flux (photons per unit area per unit time) on a small screen at a distance 2.3 m from the lamp? assume the photons are uniformly distributed over the surface of a sphere of radius 2.3 m.
