19 Consider a of nucleus to be a sphere with the nine protons uniformly distributed throughout. (a) Determine the radius of this sphere (in m). m (b) If the energy needed to assemble a uniformly charged sphere of charge Q and radius R from separate charges is U = uniformly charged sphere consisting of nine protons and with the radius determined in part (a). 3keQ² determine the energy (in MeV) needed to assemble a 5R MeV (c) Determine the binding energy (in MeV) for the nucleus 19 F. (Let the mass of a proton be 1.0078 u, the mass of a neutron be 1.0087 u, and the mass of MeV (d) Comparing your answers to parts (b) and (c), which of the following is the correct conclusion? Nuclear forces are about the same as Coulomb forces. O O Nuclear forces are much weaker than Coulomb forces. Nuclear forces are much larger than Coulomb forces. 19 F be 18.9984 u.)

Question 1 in the image attached

For questions (1) – (8) use the following information. You have measured the length of a table to be 205.0 cm, 205.8 cm, 205.4 cm, 204.6 cm, and 204.9 cm five independent times. You measured the width of the same table to be 60.1 cm, 60.4 cm, 60.2 cm, 60.0 cm, and 60.5 cm five independent times. 1) Calculate the mean length L of the table. 2) Calculate the standard deviation of the mean length σ of the table. 3) Calculate the mean width W of the table. 4) Calculate the standard deviation of the mean width ow of the table. 5) Calculate the area A = L x W of the table. 6) Using the correct equation for propagation of error, calculate the uncertainty of the area OA of the table.
