Athermocouple outputs a voltage v that depends on temperature t in k) as: v(t) = a +bt+ct2 where a = -12 v, b=0.05 v/k, and c = -1.5 10-5 v/k2. (a) [ic] find the sensitivity of the voltage output as a function of temperature. what is it at nominal body temperature to = 310 k? (b) [ic] a 12-bit analog-to-digital converter (adc) produces a digital output d. find the voltage range that is required of the adc so that the corresponding temperature range spans from 305 k to 315 k (c) estimate the temperature t as a simple linear function of the digital output d of the adc (from 0 to 1023) to be used for a reading display of the temperature sensor. (d) find the worst-case accuracy of this temperature reading over the temperature range. (e) now consider that the voltage of the thermistor is subject to additive white noise with standard deviation of 1 mv. find the precision of the temperature reading obtained from a single sample. how many samples do you need to take for each reading in order for the precision of the sample- averaged output to be better than the accuracy? (hint: think of the central limit theorem.)

The bubba chump shrimp company processes and packages shrimp for sale to wholesale seafood distributors. the shrimp are transported to the main plant by trucks that carry 1,000 pounds (lb) of shrimp. once the continuous flow processing of the shrimp begins, no inventory is allowed in buffers due to spoilage and all of the shrimp must be processed within 12 hours to prevent spoilage. the processing begins at the sorter, where the trucks dump the shrimp onto a conveyor belt that feeds into the sorter, which can sort up to 500 lb per hour. the shrimp then proceed to the desheller, which can process shrimp at the rate of 400 lb per hour. however, after 3 hours and 45 minutes of processing, the desheller must be stopped for 15 minutes to clean out empty shrimp shells that have accumulated. the veins of the shrimp are then removed in the deveining area at a maximum rate of 360 lb per hour. the shrimp proceed to the washing area, where they are processed at 750 lb per hour. finally, the shrimp are packaged and frozen. what is the daily process capacity of the processing plant (excluding the packaging and freezing)?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
