2. What is the frequency from B as heard by the listener?3. What is the beat frequency detected by the listener? Two train whistles, A and B, each have a frequency of 392 Hz. A is stationaryand B is moving toward the right (away from A) at a speed of 35.0 m/s. A listener isbetween the two whistles and is moving toward the right with a speed of 15.0m/s. (SeeFigure given). No wind is blowing.VA = 0Ug = 35.0 m/sUL = 15.0 m/sAB1. What is the frequency from A as heard by the listener?

Pd Pd 1. Let's consider a toy model of nuclear fission. Suppose an nucleus of Uranium-235 (92 protons, molar weight of 235 g/mole) "splits" into two "daughter" nuclei of Palladium (46 protons each) – this is not how it really happens, but it's a very simple model that actually gives fairly accurate results. The radius of the original U-235 nucleus is about 7.4 x 10-15 m. (a) If the Pd nuclei each have half the volume of the U nucleus, which is reasonable, and they are "touching" right after the split, how far apart are their centers? (b) Using conservation of energy, what will be the sum of the kinetic energies of the Pd nuclei when they are far apart from each other? (c) That's energy of one atom undergoing fission, so what, then, is the energy released by the fission of 1 kg of U-235? Express this in Joules and also in kilotons of TNT, where 1 kt = 4.2x1012 J. (The Hiroshima bomb yielded about 15 kt) (d) How many kwh (kilowatt-hours) of energy is this, (1 kwh = 3.6x10° J), and (if…
