Answer:
A
Explanation:
Light has both wave and particle characteristics. It behaves as wave in examples such as Reflection, refraction, diffraction, interference. It behaves as a particle in photoelectric effect, compton's effect etc. Light is an example of wave-particle duality.
Answer:
A) 1010430 pa
B) 1111755 pa
C) 2020860 N
Explanation:
Guage pressure = pgh
= 1030 kg/m3 x 9.81 m/s2 x 100 m
= 1010430 pa
Absolute pressure is Guage pressure + atmospheric pressure.
= 1010430 + 101325 = 1111755 pa
If the pressure inside submarine is 1 atm, then net pressure will be
1111755 - 101325 = 1010430 pa
Force required to open hatch against this pressure will be,
F = pghA
pgh = 1010430 pa
F = 1010430 pa x 2 m^2
F = 2020860 N
So base on your question that as if the vapors volume were to incorrectly recorded as 125ml, the effect of the error to calculate the molar mass is the same as the error in measuring the volume of the vapor. I hope you are satisfied with my answer and feel free to ask for more
