Its half life T₁/₂ = 1 hr 2 hr 3 hr 4 hr 2 / 10 The mass of a nucleus is greater than mass of nucleons less than mass of nucleons equal to nucleon mass zero 3 / 10 Fission requires high temperature strong electric field slow neutrons β particles 4 / 10 For a radioactive sample, slope of ln(N) vs t is +λ –λ +N –N 5 / 10 Which reaction gives largest ΔBE? splitting of Urenium fusion of Hydrogen isotopes β decay γ decay 6 / 10 In γ-emission, Mass number changes Atomic number changes both Mass number and Atomic number change neither Mass number nor Atomic number change 7 / 10 Binding Energy per mass number decreases for heavy nuclei because of neutron shortage nuclear force failure high binding coulomb repulsion 8 / 10 The curve of radioactive decay is straight line sinusoidal quadratic exponential decay 9 / 10 For U-235, fission produces single fragment only neutrons electrons two medium nuclei + neutrons 10 / 10 Nuclear force within a nucleus saturates because infinite range Coulomb repulsion quantum effect only each nucleon interacts with few neighbours Your score is 0% Restart quiz
