Find (a) the speed and (b) the momentum of a proton with kinetic energy 500 MeV

Lab 6- Op Amps I Brandon Tran Partner: Julien Bloch March 6 , 2017 Exercises 6.1- Comparators For this problem we built the comparator circuit shown below with R an1 R temp2rarily set to 0. As we varied the potentiometer, we saw that the output only went from -12V to 12V but nowhere in between. We could not adjust the potentiometer to obtain intermediate output voltages between -12V and 12V. It is hard to get any output voltages in between because a standard op- amp operating in open-loop configuration (without negative feedback) is used as a comparator. When the non-inverting input V is+at a higher voltage than the inve
