The evidence that the universe is expanding comes with something called the red shift<span> of light. Light travels to Earth from other galaxies. As the light from that galaxy gets closer to Earth, the distance between Earth and the galaxy increases, which causes the wavelength of that light to get longer.</span>

Explanation:

When the light coming from any object is seen through a prism or diffraction grating, we can see its spectrum consisting of 7 colors (VIBGYOR).

When the object moves towards the observer the spectrum will shift towards the blue part (decrease in wavelength) known as Blue shift and if the object moves away, the spectrum will shift towards red (increase in wavelength) known as Red shift.

Edwin Hubble, Alexander Friedmann, and Georges Lemaitre in 1920s used observed Red Shift in the celestial objects to prove that galaxies are moving away which is in line with the Big Bang theory which states that Universe started with a huge expansion and is continuously expanding. Later on observation done through Hubble Space telescope corroborated this.

Pigments are always made of natural materials
Kobotan [32]
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, the answer to the given statement is FALSE. Pigments are NOT always made of natural materials. Pigments can either be man-made or the one that occurred naturally as what you see in our environment. Hope this helps.

Lesechka [4]

Answer: 0.817A

Explanation:

Assuming , that one coulomb per second of negative charge alone flow through a conductor and no positive charges flow. I.e Q=It

It means a current of one A flow in the opposite direction.

This is similar to one coulomb per second of positive charge flowing through and there is no negative charge,

In addition, the one coulomb per second of positive charge flows. This is flowing in the current direction of the previous one. Then, the total current is 2 A. Since 2 coulomb of positive charges flow through one due to real positive charge and another due to the negative charge flowing in opposite direction.The charges cannot cancel each other, because even before the current flow the conductor was neutral.

According to this, the current in the given problem is

[2.7 + 2.4] x 10 ^ 18 * 1.602 x 10^ [-19] C/s

= 0.817 A
