Suppose that two stars in a binary star system are separated by a distance of 60 million kilometers and are located at a distanc
olya-2409 [2.1K]

Answer:The angular seperation is \theta =3.6\times 10^{-4}

Explanation:

For two objects separated by a distance 's' and at a distance 'd' from the observer the angular separation ignoring the physical effects is given by

\theta =\frac{s}{d}

In the given question

s=60\times 10^{6}km

d=180 light years

We know that in 1 light year there are 9.5\times 10^{12}km

Using the calculated values we get

\theta =\frac{60\times 10^{6}}{9.5\times 10^{12}}\\\\\theta = 6.315\times10^{-6}radians

Since π radians equals 180 degrees thus we have

\\\\\theta =\frac{6.315\times 10^{-6}\times 180}{\pi }degrees=3.6\times 10^{-4}degrees

What makes the great barrier reef special?
Kryger [21]

The Great Barrier Reef is special because it is by far the largest reef in the world. It is consisted of around 2,900 individual reefs. The size of this reef is approximately as the size of Germany. There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.

Describe the behaviour of the atmospher<br>according to temperature change​
Gekata [30.6K]
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
