A72.0-kg skydiver is falling at a terminal velocity of 79.0 m/s. which equation should be used to calculate the diver’s kinetic energy? e = mc2 me = ke + pe pe = mgh ke = ½mv2

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

This is the substance(s) formed in a chemical reaction.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
