Dc output of a r928 pmt a 400-nm dc light uniformly illuminates the photocathode of a hamamatsu r928 pmt. the photon irradiance is 10" photons per m' per s. the pmt is operated under iypicaldconditions. 12 question 1: what is the incident radiant power (in w) at the photocathode of the pmt?question 2: what is the resulting cathode current (in a)? answer question 3: what is the resulting anode current (in a)? answer question 4: it is desired that the anode current be reduced to 20 ha by decreasing the gain. what is the new gain setting and the corresponding supply voltage (in v)?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
