When a wire is stretched, an amount of work is done. What is the amount of work done in stretching a wire through 0.1 m m, if its length is 2 m and area of cross - section, 10 − 6 m 2 (Y = 2 × 10 1 1 N / m 2) 5 × 10 − 1 J; 5 × 10 − 2; 5 × 10 − 3 J; 5 × 10 − 4 J
A wire of resistivity ρ is stretched to double its length what will be its new resistivity? View Solution. Q 2. A given wire of resistance 1Ω is stretched to double its length. What will be its new resistance?
On stretching a wire its length increases but its area of cross section decreases, and volume remains constant
The pulley is frictionless, and the string is massless. Initially, the block is not hanging, it is supported by some unknown support. Also, the spring is not stretched when the block is released. When the block is released, the spring is maximum stretched. Find the ratio of tension in the rope and weight of the block (give integer value)
When a wire is stretched, its length increases by 0.3% and the diameter decreases by 0.1%. Poisson's ratio of the material of the wire is about
If a wire of 10 ohms is stretched to double its length keeping it's volume constant then what will be the new resistance? View Solution. Q5. The resistance of a wire ...
In the figure, x is the displacement from the equilibrium position. When we pull the spring to a displacement of x as shown in the figure, the work done by the spring is : W = 0 ∫ xm Fdx = -∫kx dx = -k (x m) 2 /2. The work done by pulling force F p is : Fp = k (x m) 2 / 2. The work done by the pulling force F p is in positive as it has ...
The elastic energy stored per unit volume in a stretched wire is. A wire fixed at one end is stretched by constant force F. If elongation in wire is l, then energy stored in wire will be. Stress developed in the stretched copper wire is 6 ×105 N/m2. If young's modulus of copper wire is 1.2×1011 N/m2, find the energy stored per unit volume in ...
