Chapter 36.11, Problem 1IE

The conversion between electron-volts and joules is 1 eV=1.60x10^-19 J . The work function for silver is 7.43 x 10^-19 . What is the work function for silver expressed in electron-volts?

The binding energy of an electron in a hydrogen atom is 13.6 electron volts. At what temperature will the hydrogen atom’s adiabatic index start to rise, due to the electron and proton being two particles?

4. Compute the linear attenuation coefficient of iron oxide (Fe304) at 1 MeV. Use the figures provided and the following information; µc = (Opp x Z?), PPi = g/mole, AFe NeocZ, µpe = Nope (Ope X 2"), Mрp — Nopр 11.3 g/cm³, pre304 = 5.8 g/cm³, Zp = 82, ZFe = 26, Zo = 8, Ap6 = 207.19 = 55.85 g/mole, Ao = 16 g/mole. (Note: µFe304 = µFe+ µ0).

Una barra esta empotrada en su extremo A, tiene una fuerza de 15 kN en el punto B y otra fuerza de 91 kN en el punto C. Determine la elongación o contracción en la barra AC, en mm, positivo para elongación y negativo para contracción. A = 0.0035 m² E = 200 GPa C A -5 m- 2 m B

The nucleus of an atom can be modeled as several protons and neutrons closely packed together. Each particle has a mass of 1.67 ✕ 10−27 kg and radius on the order of 10−15 m. (a) Use this model and the data provided to estimate the density of the nucleus of an atom. kg/m3 (b) Compare your result with the density of a material such as iron (ρ = 7874 kg/m3). What do your result and comparison suggest about the structure of matter?
