An object is being acted upon by three forces and moves with a constant velocity. One force is 60 N along the + x-axis, the second is 75 N along a direction making a counterclockwise angle of 150 degrees with the + x-axis. A) What is the magnitude of the third force? B) What is the direction of the third force, measured clockwise from the + x-axis?

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
