A pulsed proton beam is fireat a target each last 45.0ns and there 3.00 X 10^9 protons in each pulse, each proton having a speed of 2.50 x 10^7 m/s. All the protons hit a circular area of 2.83 X 10^-5 m^2 calle dthe beam spot. What is the average pressure on the beam spot during the pulse if the protons are absorbed by the target?
