The surface of the sun has a temperature of about 5800K and consists largely of hydrogen atoms. Find the rms speed of a hydrogen atom at this temperature. (The mass of a single hydrogen atom is 1.67×10−27kg.) The escape speed for a particle to leave the gravitational influence of the sun is given by (2GM/R)1/2, where M is the sun's mass, R its radius, and G the gravitational constant. The sun`s mass is M=1.99×1030kg, its radius R=6.96×108mand G=6.673×10−11N⋅m2/kg2. Calculate the...

Calculate the ratio of HBr molecules in the first excited vibrational state compared to the ground state at 800K. Remember that finding the probability of finding a molecule in a given state, i, is related to its energy, Ei, by the following equation: P(n) e^(-En/KT) You will need the following information to calculate the energy of the vibrational states: En = hv(n+1/2) for HBr v= 7.944*10^14s^-1 K=1.3807*10^-24J/K h=6.626*10^-34J*s
