Which statements accurately describe binary star systems? check all that apply. have more than two stars,

have stars that are always visible

include large groups of stars have stars that might appear to wobble

often have one star that is brighter than the other

- have stars that are always visible

- include large groups of stars

- have stars that might appear to wobble

Explanation:

Astronomical observations show us that in general the stars are not alone, but rather are in pairs, orbiting one around the other. This may seem strange to us, since the closest example we have, the Sun, breaks with generality, but it is so. There may also be systems with more than two stars, however, such as the Sun, they are also unlikely. Systems with more than two stars turn out to be very unstable: it is very easy for one of the stars to be thrown out of the system due to gravitational interactions, leaving only a binary system as a survivor.

Now, an important fact is that the stars of a binary system are not necessarily the same; What's more, this almost never happens. Each star is formed independently, only that they are gravitationally bound. The fact that they are gravitationally bound is what causes one orbit around the other. Here we can think of two general cases.

If the stars are far from each other, despite orbiting each other, their development will be as if they were independent stars. Your "stellar life" will not be affected by the presence of the other. In practice this happens when the separation between them is much larger than the size of the stars.

On the other hand, if the stars are close enough, then the mutual gravitational attraction can significantly affect each other's life (remember that the force of gravity goes like the inverse of the squared distance, so the farther two objects are smaller the force they exert each other, and vice versa)

Explanation:

Binary star system is the system that consist two stars which orbit around center.A star can tend to appear wobble due to small star have certain gravitational impact on larger star. It gives wobbling effect as well as one star looks more bright in comparison to other because of this effect

Other options are incorrect because multiple star system has many stars not binary star,stars are not always visible and do not have more than two stars.

heat or electricity in the atmosphere- c.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
