The speed of six different molecules in a gas are `25 m s^(-1), 20 ms^(-1), 30 m s^(-1), 15 m s^(-1), 10 m s^(-1)` and `25 m s^(-1)`. Calculate the average speed and also the root mean square of the gas. |

Answer» Average speed `(U_(av)) = (25+20+30+15+10+25)/(6) = (125)/(6) = 20.8 ms^(-1)` Root mean square speed `(U_(RMS)) = sqrt(((25^(2)) + (20)^(2) + (30)^(2) + (15)^(2) + (10)^(2) + (25)^(2))/(100)) = sqrt(950) = 21.88 ms^(-1)` |
