5. The mass of the sun is 2.00 x 1030 kg. The radius of the sunis 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 ofthe sun as two
gravitation masses each 1⁄2 the mass of the sun at the radius ofthe 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 yourUNITS first!)
f) What are the possible errors in your calculation in e)?
