Hey guys, Really confused by these problems, if anyone can answer them I will email you a coupon for a free medium 2 topping pizza from pizza hut. 1. Is it possible that two nuclei have different number of proton and different number of neutrons, but they have same nuclear radii? 2. Explain why it is important to have neutrons in a multi-particle nucleus. 3. An α particle and a β particle deflects in opposite directions in a uniform magnetic field. If both particles travel with same speed, which will show more deflection? 4. A certain chlorine isotope has its nuclear radius as 4 x 10^-15 m. Find out the number of neutrons in this isotope. 5. Find the daughter nucleus when 226/88Ra undergoes α decay. 6. Find the daughter nucleus when 234/90 Th undergoes β- decay. 7. A 14/7 N nucleus in excited state emits a γ ray with wavelength = 6 x 10^-12 m. Find the resulting decrease in mass of 14/7 N nucleus in this process. 8. A radioactive sample is placed in closed container. 2 days later only 1/4th of the sample is still radioactive. What is the half-life of this sample? 9. The bones of a tiger found to have a C-14 content that is only 15% of what would be found in a similar living animal. How old are these bones? (decay rate λ of C-14 = 3.83 x 10^-12 /sec) 10. Calculate the binding energy of α particle. 11. Complete the following reaction and find the energy it releases: 1/0 n + 235/92 U 140/54 Xe + ………. + 2 (1/0 n) What type of reaction is this?
