Homework Answers
By hydrostatic law
Pc = pressure at center of sun = 340 billion atm = 3.4 x 10^16 Pa .... google search
and Ro = radius of sun = 7 x 10^8 m
p = 3.4x10^16 x 7x10^8 / (6.67x10^-11 x 2x10^30)
= 178410 kg/m^3

Imagine a hypothetical star of radius R, whose mass density ρ is constant throughout the star. The star is composed of a classical ideal gas of ionized hydrogen, so there are free protons and free electrons flying around providing the pressure support. The star is in hydrostatic equilibrium (a) What is the pressure as a function of radius in the star, P(r)? As a boundary condition, the pressure at the surface should be zero, P(R) 0 (b) What is the...

1. For an atmosphere in hydrostatic equilibrium the variation of particle number density (# of particles per unit volume) of each species as a function of altitude (z) is found by equating gravitational and pressure forces. The resulting expression is: N(z) = No * e^(-(z - zo)/H) where N0 is a constant for each species, and z0 is an arbitrary reference altitude. The parameter H is called the scale height, which is equal to KT/mg. In the scale height expression...
The Center of Mass of the Earth-Moon-Sun System
In this problem, you will calculate the location of the center of mass for the Earth-Moon system, and then you will calculate the center of mass of the earth-Moon-Sun system. The mass of the Moon is \(7.35 \times 10^{22} \mathrm{~kg}\), the mass of the Earth is \(6.00 \times 10^{24} \mathrm{~kg}\), and the mass of the sun is \(2.00 \times 10^{30} \mathrm{~kg}\). The distance between the Moon and the Earth is \(3.80 \times 10^{5} \mathrm{~km}\). The distance between the Earth and...
