Find the values of the root mean square translational speed v, molecules in gaseous diatomic oxygen (O2), gaseous carbon dioxide

frez [133]

Answer:

539.19 m/s , 459.83 m/s , 2156.78 m/s

Explanation:

The formula for the rms speed is given by

$v_{rms}=\sqrt{\frac{3RT}{M}}$

Where, R be the gas constant, T be the absolute temperature and M be the molecular mass of the gas

R = 8.314 in SI units

T = 100°C = 100 + 273 = 373 K

For Oxygen:

M = 32 g = 0.032 kg

$v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.032}}$

vrms = 539.19 m/s

For carbon di oxide:

M = 44 g = 0.044 kg

$v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.044}}$

vrms = 459.83 m/s

For hydrogen:

M = 2 g = 0.002 kg

$v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.002}}$

vrms = 2156.78 m/s

If the oil thickness is 200 nm and the index is 1.5, what (vacuum) wavelength (in nm) does a diver see looking at the same posit

gavmur [86]

Answer: 133.33nm

Explanation: refractive index, n = real depth/apparent depth

Oil thickness= real depth = 200nm

Wavelength from under the water = apparent depth = a

n = real depth/a

1.5 = 200/ a

a = 200/ 1.5

a = 133.33nm

The average flight speed of a bald eagle is about 50 Km/h. A scientist has measured and equal flying 80 Km/h. How is this possib

Harrizon [31]

Just multiply 50Km/h to 80Km/h and your answer will be 4000 then you divide.
