 Edwin Hubble's observation of galaxies revealed that the light received from them were red-shifted, indicating that they are moving away from us. And the seemingly farther away a galaxy was, the greater its red-shift. This can only be explained if a all the galaxies were expanding outward. Determining the exact distances to the other galaxies was a problem, however, until the Hubble space telescope. It had high enough resolution to identify Cepheid variable stars in other galaxies, and accurately determine their distance, and therefore the expansion rate of the universe.eelfins <span>·

In the northern hemisphere, winds associated with a low-pressure system system blow ___. ?
Lelu [443]
<h3><u>Answer;</u></h3>

A. counterclockwise toward the center

<h3><u>Explanation;</u></h3>
  • <em><u>In the Northern Hemisphere, winds associated with a low-pressure system blow in a counterclockwise direction towards the center, while those that are associated with a high-pressure system blow in clockwise direction outwards from the center.</u></em>
  • In the Southern Hemisphere on the other hand, winds that are associated with a low-pressure system blow clockwise towards the center.
  • <em><u>The rotation of the earth creates a force called the Coriolis force, which gives the wind that is within high pressure systems a clockwise circulation in the northern hemispheres and a counterclockwise circulation in the southern hemisphere.</u></em>
