Consider an `1100` particels gas system with speeds distribution as follows :
1000 particles each with speed `100 m//s`
2000 particles each wityh speed `200 m//s`
4000 particles each with speed `300 m//s`
3000 particles each with speed `400 m//s` and 1000 particles each with speed `500 m//s`
Find the average speed, and rms speed.

Answer

A, B, C

Explanation

The average speed is
`v_(av) = ((1000) (100) + (2000) (200) + (4000) (300) +(3000) (400) + (1000) (500))/(1100)`
`309 m//s`
The rms speed is
`v_(rms) = sqrt ((1000)(100)^2 + (2000) (200)^2 + (4000) (300)^2 + (3000) (400)^2 + (1000) (500)^2)/(1100)))`
`328 m//s`.
