Gravity is a force between any two objects with mass why doesn’t a person feel a fractional force between him/herself and another person ?

Best way i know to answer it is you do! However its not alot of mass to acually feel the force,

Explanation: Lets say you weigh 150 pounds here on earth. Then you go to the moon somehow, you'd weigh 22 pounds on the moon!  There for you standing near whoever, then theres around a 0.000000000012 force pulling on you, and you don't feel it because its such a small force being pulled.

If this answer helped please mark it as right <3 ty hope this helped!

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
