Answer:
The water level will drop by about 1.24 cm in 1 day.
Explanation:
Here Mass flux of water vapour is given as
where
is the mass flux of the water which is to be calculated.
- D is diffusion coefficient which is given as
- l is the thickness of the film which is 0.15 cm thick.
is given as
In this
is the saturated water pressure, which is look up from the saturated water property at 20°C and 0.5 saturation given as 2.34 Pa
is the air pressure which is given as 0.5 times of
- R is the universal gas constant as
- T is the temperature in Kelvin scale which is
By substituting values in the equation
Converting into 
As 1 mole of water 18 
so
Putting this in the equation of mass flux equation gives
For calculation of water level drop in a day, converting mass flux as
So the water level will drop by about 1.24 cm in 1 day.
Which one are you talking about bc there's a couple
Kepler's 3rd law is given as
P² = kA³
where
P = period, days
A = semimajor axis, AU
k = constant
Given:
P = 687 days
A = 1.52 AU
Therefore
k = P²/A³ = 687²/1.52³ = 1.3439 x 10⁵ days²/AU³
Answer: 1.3439 x 10⁵ (days²/AU³)
Explanation:
These electromagnetic waves have a very small wavelength, smaller than air molecules, hence are highly prone to interference by the atmosphere when observed from the earth’s surface. Therefore there would be huge distortions to the signals carried by these waves hence rendering them unsuitable for studying space. This is why it is needed that satellites that study in the X-ray and gamma rays spectrum of electromagnetic waves are launched into space. On the other hand, examples of electromagnetic waves with relatively longer wavelength to pass through the atmosphere with little or no interruption is microwave and radio waves.
