A wire fixed at upper end

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. Work done against the external force by the deforming force. The sum of work done by the external force and the deforming force. Which one option is true? Two wires have the same material and have the same volume. However wire 1 had cross sectional area A and wire 2 has cross sectional area 3A.

Chapter 1 Solutions.

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.

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. Open in App. Verified by Toppr. Consider the coordinate system as given in the image. Velocity is increasing as x increases, i.

A wire fixed at upper end

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.
