Please show your steps clearly. . The radioactive isotope Uranium-234 decays to Thoriu-230 with a half-life of T. Thorium 230 itself is also radioactive and decays to Radium-226 with a half-life of γ and γ > τ Although Radium-226 is also radioactive its half-life is much longer than T and γ and here we assume that it is relative stable. Consider the scenario when we start with a certain amount of pure Uranium-234, because of this chain of decays, we...
hi please show your work clearly and explain, thank you! 6. Light with a frequency of 2.37 x 1015 Hz ejects electrons from the surface of platinum, which has a work function of 6.53 eV. What is the minimum de Broglie wavelength of the ejected electrons? nm
Please help with the following question. Please also show your work. D Question 18 10 pts 14. Polonium (Po) has three radioactive isotopes that are part of the decay pathway for Uranium-238 (238U), shown below. These three isotopes (2upo, 214Po, and 210Po) all decay via an alpha emmision reaction (essentially shedding a Helium atom nucleus from their own nuclei), resulting in the loss of 4 amu (e.g. 118Po à 214Pb). The rate law constants for the decay of these three...

hi please show your work clearly and explain, thank you! 10. An proton-antiproton pair is produced by a 2.20 x 100 MeV photon. What is the kinetic energy of the antiproton if the kinetic energy of the proton is 161.90 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 x 10-19 J. The rest mass of a proton is 1.67 x 10-27 kg. MeV
How to answer this question? Please write the answer clearly and concisely. Thank you! 14. A diffraction grating has 3000 lines/cm. Monochromatic yellow light (= 589 nm, i.e. 5.89 x 10 m) is incident on the grating. If this light can be seen in third order, calculate the angle at which it appears. If it cannot be seen in third order, show why not. (8 points)
