$4.2 \ m/s, 4.77 \ m/s, 4.0 \ m/s$

Vedclass · Answer

(C) Average speed $v_{av} = \frac{0 + 2 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 9}{10} = \frac{42}{10} = 4.2 \ m/s$.$rms$ speed $v_{rms} = \sqrt{\frac{0^2 + 2^2 + 3^2 + 4^2 + 4^2 + 4^2 + 5^2 + 5^2 + 6^2 + 9^2}{10}} = \sqrt{\frac{0 + 4 + 9 + 16 + 16 + 16 + 25 + 25 + 36 + 81}{10}} = \sqrt{\frac{228}{10}} = \sqrt{22.8} \approx 4.77 \ m/s$.Most probable speed $v_{mp}$ is the speed that occurs most frequently. Here,$4$ appears three times,which is more than any other value. Thus,$v_{mp} = 4 \ m/s$.

The speeds of ten particles in $ms^{-1}$ are $0, 2, 3, 4, 4, 4, 5, 5, 6, 9$. The values of average speed,$rms$ speed,and most probable speed are respectively:
