1. A ductile metal wire has resistance R. Then the wire is stretched to three times its original(poin) length. The stretching shrinks the diameter of the wire, but does not affect its density or resistivity. What is the resistance of the stretched wire? O3R 2. A current of 1.50 A flows through the leads of an electric appliance. How long does it take for (1 point) 7.50 C of charge to pass through the leads? 0 2.00s 11.0 s 6.00s...

Problem #1 A cylindrical rod of copper (E 110 GPa) having a yield strength of 240 MPa is to be subjected to a load of 6660 N. If the length of the rod is 380 mm, what must the diameter be to allow an elongation of 0.50 mm? A cylindrical specimen of some alloy 8 mm in diameter is stressed elastically in tension. A force of 15,700 N produces a reduction in the specimen diameter of 5 10-3 mm. Compute...
