Hey, I have a two part question for APY2 Physics that keeps stumping me, and I would really appreciate some
Boltzmann's constant is 1.38066×10−23 J/K. Avogadro's number is 6.02214 × 1023 /mol.
a) Determine the temperature at which the rms speed of an He atom equals 660 m/s. Answer in units of K. 009
b) What is the rms speed of He on the surface of a certain star, where the temperature is 5702 K? Answer in units of m/s.
