The velocity of a proton emerging from a Van de Graaff accelerator is 25.0% of the speed of light. What was the equivalent voltage through which it was accelerated? The mass of a proton is 1.67 \times 10^{-27} ~\text{kg}1.67×10 −27 kg. (Recall that the kinetic energy gained is equal to the electric potential energy lost as a charged particle moves through ad potential difference, ie. q \Delta V = \Delta KEqΔV=ΔKE.)

An inclined plane wrapped around a metal shaft is a a. lever b. screw c. pulley d. wedge

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Choose the most likely outcome of this scenario: jen decided to go bike riding without a helmet. while no one is around during her ride, she is thrown from her bike when her wheel goes into a pothole. she is not injured, but she is terrified to get back on her bike. what happens next? a. her physical health is affected even though she wasn't hurt. b. her mental and emotional health are affected because she is afraid to get back on her bike. c. her social health is affected because she is worried her friends saw the fall. d. her overall health is not affected at all by her fall.
