Using the discussion and equations about output resistance, develop a method to show that the output resistance of the noninverting op-amp is very small. (Hint: Determine the output voltage and current for a series of load resistors ranging from 1K to 100K, and then use equation (1.13).

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct
