1 Why does the size of the moon keep on increasing: -

 Sometimes a very big and sometimes a special small moon is visible.  Its moonlight keeps on increasing from time to time.  Why does this happen?  Read here, interesting information related to this.

The moon keeps on increasing and decreasing on the basis of its phases on the basis of fifteen to fifteen days.  Because of this, there are full moons and new moons.  The moon revolves around the earth and also rotates on its axis.  Because of this, only one side of the moon always remains in front of the earth. 

The moon has no light of its own.  It is always illuminated by the light of the sun.  The part of the Moon that is in front of the Sun when it revolves around the Earth.  That part of the moon is visible to us as shining and the rest is dark.  Which is not visible in the dark sky.  This is the reason why the size of the moon keeps on increasing.  Let us also tell you here why the stars are not visible during the day.  

Actually, the main reason for not seeing stars during the day is our atmosphere and sunlight.  During the day when sunlight hits the atmosphere, So the dust particles present in the atmosphere scatter the light here and there and the sky appears blue.  Whereas at night the light of the Sun does not illuminate the Earth's atmosphere and the light of the stars reaches the Earth.  That's why they appear.
 

2 Why most airplanes are white in color: - 

Actually, the reason behind painting the airplane with white color is that white color is a bad conductor of energy.  The airplane reflects most of the sun's rays falling on it.  

Due to this its outer surface does not get too hot.  Apart from this, if there is some kind of damage to the 4th airplane externally.  So it is easily visible.  If the ship crashes somewhere, due to its white color, it can be easily traced.  This is the reason that most of the airplanes are white in colour.  Also tell you why there are no corners in the windows of the aircraft.  Actually, in the year 1950, airplane windows used to be square.  But in the year 1953, two airplanes crashed and some people had to lose their lives. 

 The reason for the cache of these aircraft was considered to be the square windows.  Due to the square corners in the plane, the concentration of pressure at the corners of the windows increases.  Due to this the windows become weak and can crack.  Therefore the windows are made slightly curved.  Due to this, the pressure falls in the opposite direction and there is no possibility of windows cracking.
