(a) 1/8 (b) 3/4 (c) 7/8 (d) none of these29.3QQ29.4QQ29.5QQ1CQ2CQ3CQ4CQ5CQ6CQ7CQA radioactive sample has an activity R. For each of the following changes, indicate whether the activity would increase, decrease. or remain unchanged. Indicate your answers with I, D, or U. (a) The number of radioactive nuclei in the sample is doubled. (b) The half-life of the radioactive nuclei is doubled. (c) The decay constant is doubled. (d) A time period equal to two half-lives is allowed to elapse.9CQ10CQ11CQ12CQ13CQ1P2P3P4PUsing 2.3 1017 kg/m3 as the density of nuclear matter, find the radius of a sphere of such matter that would have a mass equal to that of Earth. Earth has a mass equal to 5.98 1024 kg and average radius of 6.37 106 m.6P7P8P9P10P11P12P13P14PTwo nuclei having the same mass number are known as isobars. (a) Calculate the difference in binding energy per nucleon for the isobars N1123a and M1223g. (b) How do you account for this difference? (The mass of M1223g = 22.994 127 u.)16PRadon gas has a half-life of 3.83 days. If 3.00 g of radon gas is present at time t = 0, what mass of radon will remain after 1.50 days have passed?18P19P20P21P22P23P24P25P26P27P28PThe Mass of 56Fe is 55.934 9 u, and the mass of 56Co is 55.939 9 u.
