 root mean square<span>= square root of ( 3RT/M) 

 R = 8.314 J/K/mole 
T = 25 + 273 = 298 K 
M = molecular mas of N2 in kg = 28 X 10^-3 kg 

put values... 

</span><span> root mean square</span> = square root of ( 3 X 8.314 X 298/28 X 10^-3)
= square root of ( 265454.143)
= 515.2 m/s
so option A is right
hope this helps

Given terms :

  • velocity (v) = 80 km/h

  • time (t) = 90 minutes = 1.5 hour

As we know, Distance covered is equal to :

  • velocity \times time

  • 80 \times 1.5

  • 120 \:  \: km
