SOLVE THE 3RD ONE INCLUDE ALL THE STEPS At a given temperature the rotational states of molecules are distributed according to the Boltzmann distribution. Of the hydrogen molecules in the ground state estimate the ratio of the number in the ground rotational state to the number in the first excited rotational state at 300 K. Take the interatomic distance as 1.06 Å. Estimate the wavelength of radiation emitted from adjacent vibration energy levels of NO molecule. Assume the force constant...
Solve 1st one asap At a given temperature the rotational states of molecules are distributed according to the Boltzmann distribution. Of the hydrogen molecules in the ground state estimate the ratio of the number in the ground rotational state to the number in the first excited rotational state at 300 K. Take the interatomic distance as 1.06 Å. Estimate the wavelength of radiation emitted from adjacent vibration energy levels of NO molecule. Assume the force constant k-1,550 N m In...
The interatomic spring stiffness for tungsten is determined from Young’s modulus measurements to be 90 N/m. The mass of one mole of tungsten is 0.185 kg. If we model a block of tungsten as a collection of atomic “oscillators” (masses on springs), note that since each oscillator is attached to two “springs,” and each “spring” is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is 4 times the calculated value given...
EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...
When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.67 x 10-7 m and (b) 3.99 x 10-7 m. What are the frequencies of the two lines? What color are the lines? Choose the answer that best completes the following: The existence of atomic line spectra indicates that. . . the energy of a photon depends on its frequency. all orbitals in s subshells must be spherical in shape....
Taking pure silicon (Si) as an example, explain what is meant by the terms electron-hole generation and recombination, how they affect the electrical conductivity, and define what is meant by the "intrinsic carrier density", n. [5 marks] Q3. a) b) With the aid of both lattice and energy band diagrams, explain how n-type doping of Si is achieved and state two types of suitable dopant atoms.

Please use the formulate sheet and show all steps to make sure the question is worth any points a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
