This question has statement I and statement II. Of the choices given after the statements, choose the one that best describes the two statements.
If two springs S1 and S2 of force constants k1 and k2, respectively are stretched by the same force, it is found that more work is done on the spring S1 than on spring S2

statement I If stretched by the same amount, work done on S1 will be more than that on S2

statement II k1<k2

If a simple pendulum has significant amplitude (up to a factor of 1e of original) only in the period between t=0 s to t=τ s then τ may be called the average life of the pendulum. When the spherical bob of the pendulum suffers a retardation (due to viscous drag) proportional to its velocity with b as the constant of proportionality, the average life time of the pendulum is (assuming damping is small) in sec

A metal rod of length L and mass m is pivoted at one end. A thin disc of mass M and radius R<L is attached at its centre to the free end of the rod. Consider two ways the disc is attached.
Case A -the disc is not free to rotate about its centre.
Case B-the disc is free to rotate about its centre. The rod disc system performs SHM in vertical plane after being released from the same displaced position.

A cylindrical plastic bottle of negligible mass is filled with 310 mL of water and left floating in a pond with still water. If pressed downward slightly and released, it starts performing simple harmonic motion at angular frequency ω. If the radius of the bottle is 2.5 cm, then ω is close to (take density of water =103 kg m-3),
