Astronomers believe that there is a large cloud of frozen comets called the Oort cloud, which surrounds our solar system. It lies approximately 50,000 times farther from the Sun than Earth. Approximately how many squares of toilet paper would you need to put the Oort cloud on your model? From Edmentum Earth & Space science

For you Karens & Kevins, yes I am aware that I have already posted this question. I forgot to add the photo to the last one and it wouldnt allow me to edit. DONT REPORT ME!

Explanation:

As 5 sheets represent the distance from earth to sun and the Oort cloud is 50000 times farther away,

5(50000) = 250 000 sheets

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

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.
