Can u please help me it’s for a test!! A positive and negative charge, each with a magnitude of 1.5 x 10 Care

separated by a distance of 0.15 m. Find the force on each particle.

Describe the path of a ray that approaches a mirror parallel to the principal axis.

Oxygen gas enters well-insulated diffuser at 25 lbf/in.2, 420r, with a velocity of 860 ft/s through a flow area of 1.6 in.^2. at the exit, the flow area is 12 times the inlet area, and the velocity is 19 ft/s. the potential energy change from inlet to exit is negligible. assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the following: (a) the exit temperature, in r(b) the exit pressure, in lbf/in.^2 (c) the mass flow rate, in lb/s

This battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy
