As shown below, an Insulated copper wire ia immersed in 172 g of water at 28 C. The wire is 3 em long and has a crosa-sectional area of 0.002 om. A.) Determine how much heat is needed to bring the water to a boil. The specific heat of water is 4186 3/kg K. 8.) Determine how long it will take to bring the water to a boil if a 22 A current is run through the wire. Assume all the thermal energy generated by the wire is absorbed by the water. At wire Wire Bla 5 times the length of wire A. Each wire has the same gauge a realstivity. An end of wire A ls connected to an end of wire B. The resulting wire has a reaiatance of 702 0. Determine the resistances of wires A&B RA14 R 14 O Part 2 Cross-sectional aree Wire D's cross-ectional area is 7 times the orose-sectional area of wire C. Each wire has the same length & resistivity. An end of wire Cis connected to an end of wire D. The resulting wire hasa rltance of 332 a. Determine the resistances of wires C&D. Re Ro-
