The doppler effect and redshift.

Answer:

The correct answer is red shift and Doppler effect.

Explanation:

The Doppler Effect was used by Hubble to demonstrate that the universe was expanding. According to the effect, the light from the far-off galaxies was shifted towards the lower frequencies, that is, towards the red end of the spectrum. This is known as the Red-shift or the Doppler shift.  

It was in 1925, Edwin Hubble witnessed Red-shift. He observed that the redshift of galaxies was directly equivalent to the distance of the galaxy from the Earth. This signifies that the things distant away from the planet Earth was moving away at a quicker rate, and thus, it can be concluded that the universe is expanding.

adell [148]

Answer:

Circulating air is diverted due to the Earth's rotation. Instead of flowing in a straight line, air in the Northern Hemisphere deflects to the right, whereas in the Southern Hemisphere it deflects to the left, resulting in curved trajectories. The Coriolis effect is the name for this deflection.

Bezzdna [24]

Answer:

Diffusion.

Explanation:

According to the information given before the example in the question and considering the fact that the bag was secured on both ends before being placed in the solution, provided that there were no holes on the surface of the bag, the iodine solution could have diffused through the bag into the starch solution hence the color change to black after 30 minutes.
