A sheet of copper is 1 mm thick and has surface dimensions of 5 cm × 29 cm . If the long edges are joined to form a tube 29 cm in length, what is the resistance between the ends? The mass density of copper is 8920 kg/m3 and its resistivity is 1.7 × 10−8 Ω · m . Answer in units of Ω.

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
