5. The mass of the sun is 2.00 x 1030 kg. The radius of the sun is 7.00 x 108 m.
a) What is the DENSITY of the sun?
b) What are the possible errors in your calculation in a)?
c) What is the PRESSURE at the center of the sun? (HINT: think of the sun as two
gravitation masses each 1⁄2 the mass of the sun at the radius of the sun apart.)
d) What are the possible errors in your calculation in c)?
e) What is the TEMPERATURE at the center of the sun? (HINT: use the "perfect gas
law" T = P (m/k) (1/r) where T = temperature in K0, P = pressure, m = mass of each
particle that makes up the sun (what do you think that is?), k = Boltzmann constant =
1.38 x 10-23 kg m2s-2 (K0)-1, and r is density. CHECK all your UNITS first!)
f) What are the possible errors in your calculation in e)?

Our Sun, with mass 2.00×1030 kg, revolves about the center of the Milky Way galaxy, which is 2.20×1020 m away, once every 2.50×108 years. Assuming that each of the stars in the galaxy has a mass equal to that of our Sun, that the stars are distributed uniformly in a sphere about the galactic center, and that our Sun is essentially at the edge of that sphere, estimate roughly the number of stars in the galaxy.

The mass of the sun is 2*1030 kg. It currently consists to about 70% (mass) of hydrogen. The dominant source of energy for the sun is the pp-chain (type I) fusion process in which four protons fuse into a 4He core consisting of two protons and two neutrons. This process releases 26.22 MeV ( = 4.2*10-12 J) of energy. Assume that to first order the luminosity of the sun remains constant at 1.1 times its current-day value. How long will...

A satellite of mass 2.00 x 104 kg is placed in orbit around Jupiter. The mass of Jupiter is 1.90 x 1027 kg. The distance between the satellite and the centre of Jupiter is 7.24 x 107 m. Determine the force of gravitational attraction (Fg) between the satellite and Jupiter. One of the moons of Jupiter is Io. The distance between the centre of Jupiter and the centre of Io is 4.22 x 108 m. If the force of gravitational...

A neutron star has a mass of 3.35 × 1030 kg (about the mass of our sun) and a radius of 6.09 × 103 m. Suppose an object falls from rest near the surface of such a star. How fast would it be moving after it had fallen a distance of 0.013 m? (Assume that the gravitational force is constant over the distance of the fall, and that the star is not rotating.)

Blocks A (mass 2.00 kg ) and B (mass 12.00 kg , to the right of A) move on a frictionless, horizontal surface. Initially, block B is moving to the left at 0.500 m/s and block A is moving to the right at 2.00 m/s. The blocks are equipped with ideal spring bumpers. The collision is headon, so all motion before and after it is along a straight line. Let +x be the direction of the initial motion of A....

A neutron star is an astrophysical object having a mass of roughly 2.8 × 1030 kg (about 1.4 times the mass of the sun) but a radius of only about 12 km. If you were in a circular orbit of radius 320 km (about 200 mi), how long would it take you to go once around the star? Show all steps and give reasoning.
