Question

Please try to answer in this format, thank you!

You have been able to get a part-time job in a University study the forces between nuclei in order to understand the energy output of the Sun. To do this experiment, you shoot alpha particles from a Van de Graaf accelerator at a sheet of lead. The alpha particle is the nucleus of a helium atom and laboratory. The group is planning a set of experiments to is made of 2 protons and 2 neutrons. The lead nucleus is made of 82 protons and 125 neutrons. The mass of the neutron is almost the same as the mass of a proton. To assure that you are actually studying the effects of the nuclear force, an alpha particle should come into contact with a lead nucleus. Assume that both the alpha particle and the lead nucleus have the shape of a sphere. The alpha particle has a radius of 1.0 x 10 1 cm and the lead nucleus has a radius 4 times larger. Your boss wants you to make two calculations: the lead nucleus is fixed at rest? the Van de Graaf accelerator if the alpha gas)? (a) What is the minimum speed of such an alpha particle if (b) What is the potential difference between the two ends of particle starts from rest at one end (from a bottle of helium Convince me what the answer should be before solving the problem. Explain why, using only order of magnitude estimates, proportional reasoning, drawings, and/or written explanations necessary to your explanation. If you start trying to solve the problem here, you will get no points for this box What assumptions will you have to make? NOTE: Assumptions are things that you have to assume to be the case that are NOT ALREADY GIVEN TO YOU IN THE QUESTION The algebra: Solve the problem COMPLETELY, laying out your working in a logical sequence that 1 can clearly follow (note the words "clearly follow!" USING ONLY LETTERS AND SYMBOLS AND NUMBERS THAT ARE PART OF EQUATIONS, IF YOU SUBSTITUTE ANY NUMBERS IN FOR QUANTITIES, YOU WILL GET NO CREDIT FOR THIS SECTION. The numerical solution: Substitute the values of quantities into the equations derived in the previous box to get a numerical answer. IF THE EQUATIONS YOURE SUBSTITUTING NUMBERS INTO HERE DONT APPEAR ABOVE, YOU GET NO CREDIT FOR THIS SECTION. PART 3: ASSESS YOUR ANSWER (4 points if all these boxes are convincing to me. 2 points if 2 boxes are complete and convincing to me. 0 points boxes are convincing to me) if 0 or 1 that the units on quantities Convince me your answer is in. that you plugged into equations are consistent with the units that Convince me that you've used an appropriate number of significant figures Convince me that your answer is sensible.
