A pure Si detector operating in photoconductive mode and at room temperature absorbs a 1.04MeV gamma-ray photon produced by the decay of a 136Cs nucleus. The detector has an active area of 1 cm2 and is 0.5 cm thick. (a) Compute the number of electrons generated by the absorption of this photon. (b) Compare this number with that expected to be in the CB in the absence of any illumination (this would be the background signal). Will the signal from...

A freshly brewed cup of coffee has temperature 95°C in a 20°C room. When its temperature is 74°C, it is cooling at a rate of 1°C per minute. When does this occur? (Round your answer to two decimal places.) min A population of protozoa develops with a constant relative growth rate of 0.9425 per member per day. On day zero the population consists of two members. Find the population size after five days. (Round your answer to the nearest whole number.) P(5) = members
