5. Assume that you need to measure an average temperature in a heated space. You have three identical temperature sensors. Each sensor produces a voltage proportional to temperature such that: Sensor Voltage = .01 * Temperature in degrees Celsius Assume that you bave three voltages, Va, V, and V, You want to take the average of these three voltages lin order to compute the average temperature inside the heated space. This circuit has been suggested as a possibility for computing the average. Rf ww Vout A. Find an analytical expression for Vout in terms of the input voltages and the four resistors. B. Determine if a proper dhoice of resistors will let you use this as a averager. If you can, then find some appropriate values for the resistors.

1. The sum of the resistance of resistors in series can sometimes be greater than the individual resistances. True or False 2. In planet mars the acceleration due to gravity there is also 9.81 m/s2. True or False 3. Vectors are quantity that has magnitude and direction. One example of it is density. True or False
