According to question we have to find incorrect option but
Option (a) According to Noether's theorem, law of conservation of energy is associated with symmetry of nature.
As a result of which, the amount of conserved quantity of any isolated system doesn't change, until some in flow/out flow of physical quantities takes place.
Hence, option (a) is the correct.
Option (b) As we know that, the strength of fundamental force i.e. in order of
(i) strong nuclear force
=1 (ii) electromagnetic force
=‌ (iii) weak nuclear force
=10−6 (iv) gravity
=6×10−39 ∴ Strong nuclear force and electromagnetic force
> weak nuclear force
> gravitational force.
Hence, option (b) is the incorrect.
Option (c) As we know that, the law of conservation of mass, momentum, energy etc. can only be easily observed by experimental observations.
Hence, option (c) is the correct.
Option (d) Since there are two types of nuclear reaction i.e. nuclear fission fusion and in both cases we find generation of energy due to breaking of heavy nuclei
(U235) or by fusion of two light nuclei i.e.
(H12 and
H13), respectively.
