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 11.7 0, and that a hot dog requires 74.0 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. Quick! Get to work! (a) Determine which hot dog(s) will cook first. (Select all that apply.) o the single hot dog This combination will be among the first to cook, but there is another combination that cooks at the same time. o the two hot dogs in series O the two hot dogs in parallel (b) Determine the time interval (in s) for each hot dog to cook.
