(A) Slow neutron can cause fission in 92235U than fast neutrons because fast neutrons are too quick so they scatter of atoms instead of being captured by them (B) α-rays are Helium nuclei, is a true statement (C) β-rays are generated when neutron is converted into proton by releasing electron or proton is converted into neutron by releasing positron. (D) γ-rays have higher energies as compared to X -rays. So they have smaller wavelength as compared to X-rays.
Select the correct statements among the following : A. Slow neutrons can cause fission in _92^235 U than fast neutrons. B. α-rays are Helium nuclei.…
