At a certain temperature the speeds of six gaseous molecules in a container are 2.0 m/s, 2.2 m/s, 2.6 m/s, 2.7 m/s, 3.3 m/s, and

iren [92.7K]

Answer:

root-mean-sqaure = 2.77 m/s

average = 2.72 m/s

The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.

Explanation:

The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.

$R = \sqrt{\frac{x1^2 + x2^2 +...+xn^2}{n} }$

$R = \sqrt{\frac{(2.0)^2 + (2.2)^2 + (2.6)^2 + (2.7)^2 ^(3.3)^2 + (3.5)^2}{6} }$

R = √(46.03)/6

R = 2.77 m/s

The average speed is the sum of the speeds divided by the number of datas:

$A = \frac{2.0 + 2.2 + 2.6 + 2.7 + 3.3 + 3.5}{6}$

A = 16.3/6

A = 2.72 m/s
