Question

Four molecules of gas are having speeds of 1, 4, 8 & 16 ms^-1. Find root mean square velocity of the gas molecules?​

Answer 1

Answer:

9.2 m/s

Explanation:

Root mean square velocity = $\frac{\sqrt{x^{2} + y^{2} + z^{2} + a^{2} } }{\sqrt{4} }$

= √(1² + 4² + 8² + 16²)/√4

= √(337)/2 m/s

= √(84.25) m/s

= 9.2 m/s
