- Data from the appendices and the periodic table may be needed for these problems. Mantles for gas lanterns contain thorium, because it forms an oxide that can survive being heated to incandescence for long periods of time. Natural thorium is almost 100% 232Th.Questions deal specifically with hydrogen.As discussed in the video, so long as you’re using the constants from the PRC, these answers shouldtechnically have an infinite number of significant figures by the assumptions of the course. Report allof them to at least four significant figures to ensure full credit. As always, unless otherwise stated,numerical entry problems require the answer to be in units that are the SI standard for whateverquantity they’re measuring (lengths, for instance, are reported in m, notnm,μm, km, etc.). Convert tostandard units if necessary, but do not include the unit in the answer field.Remember that the way you can be positive Blackboard understands your numbers, if you choose towrite them in scientific notation, is to use “E” in place of “10^.” That is, if you find that a particularfrequency is1.234×1014Hz, it would be entered as1.234E14 1) Calculate the wavelength of thelight that creates thethird line in the Balmerseries.Questions deal specifically with hydrogen.As discussed in the video, so long as you’re using the constants from the PRC, these answers shouldtechnically have an infinite number of significant figures by the assumptions of the course.

- Seawater contains 3 mg of uranium per cubic meter. (a) Given that the average ocean depth is about 4 km and water covers two-thirds of Earth’s surface, estimate the amount of uranium dissolved in the ocean. (b) Estimate how long this uranium could supply the world’s energy needs at the current usage of 1.5 × 1013 J/s. (c) Where does the dissolved uranium come from? Is it a renewable energy source? Can uranium from the ocean satisfy our energy requirements? Discuss. Note: Breeder reactors increase the efficiency of nuclear fuel use by approximately two orders of magnitude.HI, CAN U PLS MAKE A DETAILED SOLUTION FOR THIS PROBLEM THANK YOUA particle has γ=18,399. a) Calculate c-v in m/s. (I would have asked for 1 - v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1 - v/c) and use an approximation. b) In a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle. We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light. ("Massless particles" -- gamma and m have to be eliminated from the expressions. Light is a true massless particle.) If a massless particle has momentum 1,739 MeV/c, calculate its energy in MeV. Thank you so much!!
