Question: Critical Thinking Two boxes of the same mass are pressed against pistons that compress and release the boxes on frictionless surfaces. Box A’s piston has a constant force F over a distance _x_ before the box is released while box B starts at zero force and increases linearly to a force of 2 _F_ before releasing the box at a distance of 1/2 _d_ . (a) Which of these boxes has the greatest speed after releasing from the piston? (b) Based on experimental data for trials similar to box A, an equation that fits the data is suggested for the change in kinetic energy, \Delta KE , which may not be correct: \Delta KE = KF^{1/2}x^{1/2} , where _K_ is a constant with appropriate units, _F_ is the applied force, and _x_ is the distance the piston moves in contact with the box. Is this equation consistent with your answer from part a? Explain why or why not. Does this equation make sense? Explain why or why not. (c) If the applied force of the piston is proportional to the distance in contact with the box, graph the work done on the box vs. the distance in contact with the piston and box.

Question: There are two important isotopes of uranium, {}^{235}\text{U} and {}^{238}\text{U} ; these isotopes are nearly identical chemically but have different atomic masses. Only {}^{235}\text{U} is very useful in nuclear reactors. Separating the isotopes is called uranium enrichment (and is often in the news as of this writing, because of concerns that some countries are enriching uranium with the goal of making nuclear weapons.) One of the techniques for enrichment, gas diffusion, is based on the different molecular speeds of uranium hexafluoride gas, \text{UF}_{6} . (a) The molar masses of {}^{235}\text{U} and {}^{238}\text{UF}_{6} are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their typical speeds v_{\text{rms}} ?
