A wire fixed at upper end

A uniform metallic rod rotates about its perpendicular bisector with constant angular speed.

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 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. The force F is so adjusted that the wire is only slowly stretched. A telephone switchboard pair cable can be made up with either enameled wire or tinned wire.

Step 1: Recall the formula for work done Work done is the product of force and the distance moved in the direction of the force. The combined wire is stretched by applying a force. Non-necessary Non-necessary.

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.

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?
