Answer:
Explanation:
As we know that rms speed of ideal gas is given by the formula
here we know that
molecular mass of gas is given as
now from above formula we have
now we have
The dimension of a/b where x is the distance and t is the time is T
Given the expression
x = at + bt²
where
x is the distance
t is the time
Based on the homogeneity principle, the expression on the left-hand side must be equal to that on the right. Hence;
x = at
Since x is the distance and distance is measured in metres, the dimension equivalent will be the length 'L'
Since t is the time and time is measured in seconds, the dimension equivalent will be the seconds 'T'
Similarly;
x = bt²
Next is to get a/b;
Hence the dimension of a/b is T
