Question

Calculate the rms speed of helium atoms near the surface of the Sun at a temperature of about 5100 K. Express your answer to two significant figures and include the appropriate units.

Answer 1

`V_(rms)=5.6*10^3m/s`

Step-by-step explanation:

From the question we are told that:

Temperature
`T=5100K`

Generally the equation for RMS Speed is mathematically given by

`V_(rms)=\sqrt{(3kT)/(m)}`

Where

`K=Boltzman's constant`

`K=1.38*10^(-23)`

And

`M=molecular mass`

`M=4*1.67*10^(-27)`

`V_(rms)=\sqrt{(3(1.38*10^(-23))5100)/(4*1.67*10^(-27))}`

`V_(rms)=5.6*10^3m/s`
