a thermocouple consists of two wires made of dissimilar metals that are joine logether to form an electrical circuit. a thermal electromotive force (emf) e i generated when the two junctions are at different temperatures. when one jund tion is held at the ice point and the other is at a celsius temperature of t, th thermometric function is given by where is in millivolts. calculate the constants a and b for a thermocouple read ing 60 mv at 200Β° c and 40 mv at 400pc. what temperature corresponds to reading of 30 mv?

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
