Light of wavelength 400 nm and a power of 1.83 x 10-6 w is incident onto a photodetector with quantum efficiency 0.57. the sensor is connected to a 5.7 k52 load resistor and operated at a temperature of 300 k. (a) determine the responsivity of the detector. (b) determine the photocurrent produced by the detector. (c) if the sensor is connected to a 5.7 ks2 load resistor, determine the voltage generated across the load resistor from this photocurrent. (d) if the detector is dominated by johnson noise and has a measurement bandwidth of 1 mhz, estimate the snr.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
