A copper wire of cross-sectional area 0.01 cm2^2 is subjected to a tension of 22 N. If Young’s modulus and Poisson’s ratio of copper are 1.1×10111.1 \times 10^{11} Nm2^2 and 0.32 respectively, then the change in the cross-sectional area of the wire is:
A body of mass 3 kg is thrown vertically upward from the ground with a velocity of 10 ms−1 10 \, \text{ms}^{-1} . If the maximum height reached by the body is 4.7 m, then the loss of energy due to air resistance is:
A cannon fires two similar shells one after the other each with a velocity of 100 m/s at angles 60∘^\circ and 30∘^\circ respectively with the horizontal such that they both hit the target at the same time. The time interval between the firing of the two shells is (Acceleration due to gravity = 10 m/s²).
An arc making an angle 15∘15^\circ at the center is removed from a ring of mass M M and radius R R . The moment of inertia of the remaining ring about an axis passing through its center and perpendicular to its plane is:
