Consider aWheatstone bridge circuit using a resistive temperature sensor Rx as shown
in Figure 1.2. Further assume that R1 = 10 and R3 = 20. Assume that the current
temperature is 80 ◦F and Rx (80) = 10. You wish to calibrate the sensor such that the
output voltage VOUT is zero whenever the temperature is 80 ◦F.
(a) What is the desired value of R2?
(b) What is the output voltage (as a function of the supply voltage) at a temperature of
90 ◦F, when this increase in temperature leads to an increase in resistance of 20%
for Rx?
a car starting from rest travel 100m in 8 second assuming constant accleration find the average speed for these 8 second what is the accleration and the distance covert in the first 5 seconds
A 12,600 kg railroad car travels alone on a level frictionless track with a constat speed of 18 m/s. A 5350 kg load, initially at rest, is dropped onto the car. What will be the car´s new speed? *
