Which of the following statements (s) is (are) correct?

The rest mass of a stable nucleus is less than the sum of the rest masses of its separated nucleons

The rest mass of a stable nucleus is greater than the rest masses of its separated nucleons

The nuclear fusion, energy is released by fusing two nuclei of medium mass. (approx. 100 am u)

In nuclear fission, energy is released by fragmentation of a very heavy nucleus.

A plot of log `K_(P)` versus `1//T` is linear

A plot of log `[X]` versus time is linear for a first order reaction , `X`, `P`

A plot of log `P` versus `1//T` is linear at constant temperature

A plot of `P` versus `1//V` is linear at constant temperature

In an inertial frame `W_("conservative") +W_("non-conservative") + W_("other -force") = K _(2) - K_(1)`

In a non - inertial frame : `W_("conservative") +W_("non conservative ") +W_("other -force") +W_("pseudo - force ") = K_(2) - K_(1)`

Work done by conservative forces is independent of path followed .

Work done by non - conservative forces depends on path followed .
