The above is a plot of binding energy per nucleon Eb, against the nuclear mass M; A, B, C, D, E, F correspond to different nuclei. Consider four reactions:

where ε is the energy released? In which reactions is ε positive?

A piece of wire is bent in the shape of a parabola y = kx2 (y-axis vertical) with a bead of mass m on it. The bead can slide on the wire without friction. It stays at the lowest point of the parabola when the wire is at rest. The wire The wire is now accelerated parallel to the x-axis with a constant acceleration a. The distance of the new equilibrium position of the bead, where the bead can stay at rest w.r.t. the wire, from the y-axis is

When a lift is moving upward with acceleration of 5 m/s2 then percentage change in the weight of the person in the lift is x%. If the lift is moving down with acceleration 5 m/s2 then percentage change in the weight of
same person is y%. Then the ratio x/y is (g = 10 m/s2)
