Q1. The breaking stress for a wire of radius 'r' of given material is F N/ms square. Afterwards find the breaking stress for the wire of same material of radius 2r?
Q2. A 2.46 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 110 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 10.4 m/s, while spring is at first unstrained. What is the amplitude of the resulting simple harmonic motion?
