It must measure the supergranules. This refers to the physical pattern casing the exterior of the quiet Sun with an archetypal horizontal scale of approximately 30,000 km and a lifetime of around 1.8 d. Its most noticeable or visible signature is as a fluctuating velocity field of 360 m st-1 rms whose components are mostly horizontal. This was exposed more than fifty years ago, conversely clearing up why and how it originates still represents one of the core challenges of modern solar physics.

Which is a mark of a galaxy formed by collapse?

postnew [5]

Answer:

Same age stars is a mark of a galaxy formed by collapse.

Explanation:

Before a galaxy is formed, the building material of the galaxy in a protogalactic cloud that is rotating at a great speed rapidly accumulates and collapses in itself owing to its own gravitational pull.

With this collapse, globular clusters are formed away from the nucleus of the galaxy.

These clusters give birth to halo stars more or less at the same time. Thus, the stars that are formed of the same age.

Sometimes, the reference of the age of the stars is taken to determine the age of the entire galaxy.

In 2 ways how does proximity to water affect politics? (will mark brainliest)

dedylja [7]

Water has everything to do with politics, mainly because of large bodies of water being ports or pathways for ships to cross, it can lead to policies revolving around trade and taxes on imported goods.

If someone were campaigning someone could promise to reduce pollution in the area near the water, and promise to clean the water up and grab votes from the environmentalists or locals that (may) drink from the water or use it in some way.
