When you join a p-type semiconductor with an n-type semiconductor to form a p-n junction, holes initially flow from the p-type material into the n-type material, and electrons flow in the opposite direction. Why? a) There is an electric field because of the positive charge in the p-type material and the negative charge in the n-type material. b)Each diffuses into the region where it is at lower concentration. c)The n-type material is at lower potential. d)The n-type material is at...

How do I get the change in V? why is it 1.5? Also why is change in T equal to 84? When I did the experiment, I obtained: Temp (°C) Vol (mL) T(K) 22 62 Room temp Hot bath Ice bath Alcohol bath 6.0 6.8 5.6 5.3 295 335 275 2 -22 251 m = (change in V) + (change in T) = 1.5 + 84 = 0.018 so: V = 0.018 T+C

A helical spring with stiffness k = 20 N / mm becomes locked when pressed with δB = X mm. The spring diameter ratio is Ck = D / d = 8 and in case of locking, the spring is dimensioned, locking and releasing, provided that the stresses do not exceed τb = 455 N / mm2. Calculate the spring lengths in the state. The spring sliding module is given as G = 80800 N / mm2. The spring is...
