Today's class on current and resistance is about to begin and you await your professor, who is known for unorthodox demonstrations. he walks in just at the beginning time for the class, and is carrying hot dogs! he then proceeds to set up a demonstration using an older style of hot dog cooker in which the hot dogs are directly connected across 120 v from the wall socket. he has modified the cooker so it simultaneously applies the 120 v to three combinations: across the ends of a single hot dog, across the ends of two hot dogs in parallel, and across the outer ends of two hot dogs in series. he explains that he has measured the resistance of a hot dog to be 12.6 ω, and that a hot dog requires 79.0 kj of energy to cook it. he says he will give extra credit to anyone who, before any hot dog begins smoking, can determine which hot dog(s) will cook first, and the time interval for each hot dog to cook.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
