A wire of unknown material with a cross-sectional area of 1 mm^2 and an unstretched length of 0.5 m is stretched through the application of known forces. From the plot of force as a function of Delta L in the figure, the Young's modulus of the material is: A. 4 times 10^10 N/m^2 B. 80 N/m^2 C. 40 N/m^2 D. 8 times 10^10 N/m^2 E. none of the above
A copper wire of cross-sectional area 2.50 times 10^-6 m^2 and length 4.00 m has a current of 2.00 A uniformly distributed across that area. (a) What is the magnitude of the electric field along the wire? (b) How much electrical energy is transferred to thermal energy in 40.0 min?
Please answer #5. Show all work. . A 10 kg load suspended by a brass wire 10 m long is observed to vibrate vertically in SHM at a frequency of 10 vibs. Given that the Young's modulus for brass is 9x 1010 N/m', what is the cross-sectional area of the wire?
A 107 kg mass suspended from a wire whose unstretched length is 4.05 m is found to stretch the wire by 6.40 mm . The wire has a uniform cross-sectional area of 0.130 cm2. a) If the load is pulled down a small additional distance and released, find the frequency at which it vibrates (in Hz). b) Compute Young's modulus for the wire.
You apply a force of magnitude F⊥ to one end of a wire and another force F⊥ in the opposite direction to the other end of the wire. The cross-sectional area of the wire is 8.00 mm2. You measure the fractional change in the length of the wire, Δl/l0, for several values of F⊥. When you plot your data with Δl/l0 on the vertical axis and F⊥ (in units of N) on the horizontal axis, the data lie close to...
2) A light bulb filament is made of tungsten. It has a cross sectional area of 1.7 x 10-m and a length of 0.02 m. What tension force should you apply to the filament to stretch it by the diameter of 1 tungsten atom, which is 2.1 x 10-10 m? The Young's modulus for tungsten is 3.6 x 1011 N/m² (4 points)
