How to figure out how much power is dissipated

Reference no: EM139008

Q1. Your toaster has a power cord with a resistance of 0.016 connected in series with a 10.6 nichrome heating element. The potential difference between terminals of the toaster is 120v how to figure out how much power is dissipated in the power cord?

Q2. One mole of titanium (6 x 17^23 atoms) has a mass of 46 grams, and its density is 4.04 grams per cubic centimeter, so the center-to-center distance between atoms is 2.60 10-10 m. You have a long thin bar of titanium, 2.8 m long, with a square cross section, 0.11 cm on a side.

You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
