Hello i have a problem with this question if anyone could help me ,that would be great.
Estimate the thermal velocity of particles in the solar corona (take a distance two times the radius of the sun and assume that the particules have only two degrees of freedom),
thus the thermal energy is calculated via Eth = kB*T where kB is boltzmann constant.
Thank you.

Do you know the temperature?
There is a relation between temperature and average/squared average/whatever velocity.

hmmm well it's not precised but the average temperature in the corona is 10^6 K, i guess it will do.
