The net potential energy en between two adjacent ions is sometimes represented by the expression e, m3 + d exp (2.18) in which r is the interionic separation and c, d, and rho are constants whose values depend on the specific material (a) derive an expression for the bonding energy eo in terms of the equilibrium interionic separation ro and the constants d and p using the following procedure: (i) differentiate en with respect to r, and set the resulting expression equal to zero. (ii) solve for c in terms of d, p, and ro i) determine the expression for e by substitution for c in equation 2.18 (b) derive another expression for eo in terms of ro, c, and p using a procedure analogous to the one outlined in part

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656(red) and 486 (blue). light from a hydrogen lamp illuminates a diffraction grating with 500 lines per mm, and the light is observed on a screen 1.50 behind the grating. what is the distance between the first-order red and blue fringes?
