<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here I'll assume that you want the interpretation of the expression:

s\times s

The easier interpretation is that we are talking about a square of sides s so the given expression would represent the area of the square. In other words:

A=s\timess \\ \\ A=s^2

For instance, if we have a square of sides s=4cm then the area would be:

A=4\times 4 \\ \\ A=16cm^2

The figure below shows the representation of this problem.

Kisachek [45]

How do we know there is Dark Matter in other galaxies? a. it occasionally lum inesces b. flat rotation curves in spiral galaxies
lesantik [10]

Answer:

b. flat rotation curves in spiral galaxies

Explanation:

Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.

Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.  

The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.  

Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
