Answer:
The SI units for energy is Joules.
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
Acceleration= change in velocity/time; 5/2.8 , so a=1.785714286
The answer is C. Watson and Crick developed the Double Helix model seen in the diagram.
