A wire fixed at the upper end stretches by length l by applying a force F. What is the work done in stretching? Facebook LinkedIn Pinterest. The elastic potential energy of a body is 1. Work done by the external force against the deforming force.

A wire fixed at upper end

A bob of mass 10 kg is attached to wire 0. Its breaking stress is 4. The area of cross-section of the wire is 10 -6 m 2. The maximum angular velocity with which it can be rotated in a horizontal circle is. A rubber cord 10 m long is suspended vertically. How much does it stretch under its own weight? A brass rod of cross-sectional area 1 cm 2 and length 0. The work done in stretching is. A one-metre long steel wire of cross-sectional area 1mm 2 is extended by 1 mm. A wire of diameter 1 mm breaks under a tension of N. Another wire, of same material as that of the first one, but of diameter 2 mm, breaks under a tension of :.

Chapter 5 Solutions. Signup with Email. The wire B is stretched more than A and also comes back to its original length when the stretching force is removed.

An elastic spring of unstretched length L and spring constant K is stretched by a small length x. It is further stretched by another small length y. An elastic spring of unstretched length L and force constant k is stretched by a small length x. The work done in the second stretching is. Two wire of same material and same diameter have lengths in the ratio 2 : 5. They are stretched by same force. The ratio of work done in stretching them is.

Provided the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about How far apart would the dots be in each set? Could you readily measure their separation with a meter stick? On December 26, , a great earthquake occurred off the coast of Sumatra and triggered immense waves tsunami that killed some , people. Satellites observing these waves from space measured km from one wave crest to the next and a period between waves of 1. Does your answer help you understand why the waves caused such devastation? Waves above this frequency can be used to penetrate the body and to produce images by reflecting from surfaces. For a good, detailed image, the wavelength should be no more than 1. What frequency sound is required for a good scan? What is the range of the wavelengths of audible sound in air?

Use app Login. A perfectly elastic uniform string is suspended vertically with its upper end fixed to the ceiling and the lower end loaded with the weight. If a transverse wave is imparted to the lower end of the string, the pulse will: travel upwards with decreasing speed travelled upwards with constant acceleration travel upwards with increasing speed not travel along the length of the string.
