The surface of the sun has a temperature of about 5800K andconsists 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 gravational influenceof the sun is given by (2GM/R)^1/2, where M is the sun's mass R itsradius, and G the gravational constant. The sun's mass isM=1.99*10^30 kg, its radius R= 6.96*10^8m And G=6.673*10^-11n*m^2/kg^2.

Calculate the escape speed for the sun

11: How fast would you need to travel a) to escape the gravitational pull of the sun? b) As the sun begins to die, it will become a red giant. This means that its mass will remain the same but its diameter will increase substantially. When the sun becomes a red giant will its escape speed be greater than, less than, or the same as it is now?

12: How fast would the moon need to travel in order to escape the gravitational pull of the Earth, if Earth has a mass of 5.98 X 10^24 kg and the distance from Earth to the moon is 3.84 X10^8 m?

The escape velocity from the Moon is much smaller than from Earth and is only 2.38 km / s. At what temperature would hydrogen molecules( molecular mass is equal to 2.01 g/mol ) have an average velocity v_rms equal to the moon's escape velocity?
