It is desired to produce a p-type semiconductor out of Group IV silicon that will have an electrical conductivity of 100 (?·m)-1 at room temperature. Assume that the mobility of electrons in silicon is equal to 0.10 m2 /V·s, and the mobility of holes is equal to 0.03 m2 /V·s. You may assume that this semiconductor is in the extrinsic range of operation at this temperature.
(a) What is the required density of holes in the valence band? (b) What concentration of substitutional acceptor atoms will produce the desired electrical conductivity, assuming that an element from Group III is substituted for the silicon atoms?

High-speed stroboscopic photographs show that the head of a golf club of mass 200 grams is traveling at 55.0 m/s just before it strikes a 46.0-gram golf ball at rest on a tee. After the collision, the clubhead travels (in the same direction) at 40.0 m/s. Find the speed of the golf ball just after impact
A battery is attached to several different capacitors connected in series. Which of the following statements is true?
1.All capacitors have the same charge, and the equivalent capacitance is greater than the capacitance of any of the capacitors in the group. 2.The capacitor with the largest capacitance carries the smallest charge. 3.The potential difference across each capacitor is the same, and the equivalent capacitance is greater than any of the capacitors in the group. 4.The capacitor with the smallest capacitance carries the largest charge. 5.The potential differences across the capacitors are the same only if the capacitances are the same.
