This question contains Statement - 1 and Statement -2 Of the four choice given after the Statements , choose the one that best decribes the two Statements Statement- 1: Energy is reased when heavy underge fission or light nuclei undergo fasion and Statement- 2: for nuclei , binding energy nucleon increases with increasing Z while for light nuclei it decreases with increasing Z

Assertion: Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. Reason: For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z.

This questions has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes into two Statements. Statement-I : Higher the range, greater is the resistance of ammeter. Statement- II : To increase the range of ammeter, additional shunt needs to be used across it.

This question contains Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements. Statement-1: For a charged particle moving from point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connecting point P to point Q. Statement-2: The net work done by a conservative force on an object moving along a closed loop is zero.

This question has statement - 1 and statement - 2 of the four choice given after the statements choose the one that best describes the two statements statement - 1 : A metallic surface is irradiated by a monochromatic light of frequency v gt v_(0) (the threshold frequency). The maxim,um kimetic energy and the stopping potential are K_(max) and V_(0) respectively if the frequency incident on the surface is doubled , both the K_(max) and V_(0) are also doubled statement - 2 : The maximum kinetic energy and the stopping potantial of photonelectron emitted from a surface are linearly dependent on the frequency of incident light

This question has statement I and statement II. Of the four choices given after the statements, choose the one that best describes the two statements. Statement I: A point particle of mass m moving with speed v collides with stationary point particle of mass M. If the maximum energy loss possible glven as f(1/2mv^2) then f=(m/(M+m)) Statement II: Maximum energy loss occurs when the particles get stuck together as a result of the collision.

This question has statement 1 and statement 2 . Of the four choice given after the Statement , choose the one that best describe the two Statement . If the spring S_(1) and S_(2) of force constant k_(1) and k_(2) respectively , are streached by the same force , it is found that more work is done on spring S_(1) then on spring S_(2) Statement -1: If statement by the same answer work done on S_(1) work on S_(1) is more then S_(2) Statement - 2 : k_(1) ltk_(2)

Choose the correct from the following. A) Large mass number nuclei undergo fission B) Low mass number nuclei undergo fusion C) For heavy nuclei the decrease in binding energy per nucleon shows the contribution of the increasing coulomb repulsion.
