<u>Answer:</u>
The gauge pressure is 6670.8 Pascal
<u>Explanation:</u>
Given the height is 0.68 m
The Gauge pressure is determine by the formula,
Gauge pressure , P = hdg
Where h = 0.68 m
d = 1000
g = 9.81
Substituting the values in the formula of Gauge pressure, we get
Gauge Pressure = hdg =
Gauge Pressure = 6670.8
Therefore, the gauge pressure is 6670.8 Pascal
freezing
During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid. Because particles in a liquid have more energy than particles in a solid, energy is released during freezing. This energy is released into the surroundings.
I would say gas, but I don't know enough about plasma to put it out. It's definitely not solids or liquids because their molecules are too close together to move freely. Gas or plasma! Sorry that I'm not sure.
Answer:
Option C ⇒ D=2λr is the correct answer, since it has the largest aperture diameter.
Explanation:
Regarding Rayleigh's criterion, the angular resolution is given as below:
θ = 1.22λ/D
From this expression, it is observed that the larger the aperture size, the smaller will be the value of the angular resolution, and the better the device will be.
This signifies that at very high angular differences, the precision for distinguishing two points is high.
Therefore, option C ⇒ D=2λr is the correct answer, since it has the largest aperture diameter.
