Answer:
515.22 m/s
Explanation:
Formula for root mean square velocity is SQRT (3RT/M)
Where,
R = Rydberg's constant = 8.314 Kg. m²/ s². K. mol
T = Temperature in Kelvin
M = Molar mass in Kg/mol
First calculate molar mass,
As nitrogen is diatomic molecule,
Its molar mass is
M = 2(14) = 28 g/mol
Convert unit into Kg/mol
28 g/mol x 1 Kg/1000g = 2.8x10¯² Kg/mol
Convert temperature into kelvin
T = 25 + 273 = 298K
Put all values in formula
Vrms = SQRT (3RT/M)
Vrms = SQRT (3x8.314x298/2.8x10¯²)
Vrms = SQRT (265454. 14)
Vrms = 515.22 m/s

Given :
Whole-body dose of 8.4 mGy from gamma-rays and 1.2 mGy from 80-Kev neutrons.
To Find :
The effective dose to a worker.
Solution :
By the given information effective dose to a worker is given by :
E.D = ( 8.4 × 1.2 × 0.12 ) + ( 1.2 × 1 × 1 )
E.D = 1.2096 + 1.2
E.D = 2.4096
Therefore, the effective dose to a worker is 2.4096 .
Its easy to create a visual and see major differences between data. If something takes up a large portion of the pie, its easy for you to tell just by looking at it
