mp 3. | Density of the nucleus. (a) Using the empirical formula for the radius of a nucleus, show that the volume of a nucleus is directly proportional to its nucleon number A. (b) Give a reasonable argu- ment concluding that the mass m of a nucleus of nucleon number A is approximately m = mp4, where m, is the mass of a proton. (c) Use the results of parts (a) and (b) to show that all nuclei should have about the same density. Then calculate this density in kg/m³, and compare it with the density of lead (which is 11.4 g/cm³) and a neutron star (about 10¹7 kg/m³). View Inspector Zoom Share Highlight Rotate Markup JIS.)

1. The decay of radioactive substance is given by 7 N = Noe (1), where N is the number of atoms present at time t, No is the initial number of atoms and T is the exponential decay constant, which is related to the decay rate of the element. The N 1 half-life thalf is the time required for the number to atoms to decay by half ( = No 2 Solve for thalf starting from equation (1) in terms of T. Note: Use MathType to enter in T. Do not use the letter "T" from the keyboard. Don't forget the multiplication sign between variables. Use the asterisk symbol (*) for multiplication or the multiplication symbol in the math editor (orange box). thalf = 0.693 X√ S No, that's not the correct answer.

Q1) As of early 1981, approximately 1500 000 litres (1500 m³) of radioactive water were located in the basement of the containment building of the Three Mile Island Unit 2 nuclear plant. One of the principal sources of this radioactivity was ¹37Cs measured μCi at 1565 cm3. Calculate how many atoms per cm³ of this radionuclide were in the water at that time? The half life of 137Cs is 30 years.

NUCLEAR CHEMISTRY: Consider the nuclei Sn with an atomic number of 50 and mass number is 117 . Determine its mass defect in kilograms if its atomic mass is 116.956 amu. The mass of a proton and neutron are 1.0073 and 1.0087 amu, respectively. Express your answers in three decimal places in scientific notation, i.e., 6.022e23 to represent 6.022x 105
A living specimen in equilibrium with the atmosphere contains one atom of 14C (half- life = 5 730 yr) for every 7.7 x 1011 stable carbon atoms. An archeological sample of wood (cellulose, C12H22011) contains 27 mg of carbon. When the sample is placed inside a shielded beta counter with 89% counting efficiency, 837 counts are accumulated in one week. Assuming that the cosmic-ray flux and the Earth's atmosphere have not changed appreciably since the sample was formed, find the age of the sample in the nearest year (1 yr ~ 3.1536 × 10' s).
