Answer:
Explanation:
We have the relation of continuity equation as for compressible fluid flow:
where:
density of the fluid
A = area of cross-section of the fluid flow
v = velocity of flow
For a compressible fluid, the density varies.
It is also called mass flow rate, having unit as kilogram per second and is proportional to density.
The higher the density more is the mass flow rate of the fluid.
AnswerAmontons's law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1).:
Explanation:
Answer:
blue star is hotter than red
Explanation:
The colour of a star depends on its temperature.
Lesser the temperature means lesser be the energetic. less energy means longer wavelength. Between blue and red, red colour has longer wavelength. So, the red colored star is colder than blue coloured star.
Blue coloured star is hotter than red coloured star.
