Answer: 10 parsecs</h2>
Parallax is the angle formed by the observation lines to a very distant object from two separated points.
The procedure to measure this distance in the case of a star, is based on observing it from two different places far away from each other, and then through trigonometry reach to the following relationship:
(1)
Where:
is the distance from Earth to the observed star (in Parsecs )
is the earth-sun distance that is equivalent to an astronomical unit (1AU=150000000km)
is the angle of the parallax (in arc seconds )
Now, the distance to an object (measured in parsecs) is the reciprocal of the parallax (measured in arcseconds).
Then, in its simplified mode, the stellar parallax is given by the following equation:
(2)
<u>Finally we have the distance to the star:</u>
The Ring of Fire is a ring of volcanoes around the Pacific Ocean that result from subduction of oceanic plates beneath lighter continental plates. Most of the Earth's volcanoes are located around the Pacific Ring of Fire because that the location of most of the Earth's subduction zones.
When the population is going to increase, the demand of resources like cars, houses, etc is going to increase as well. A lot of trees are going to be cut down to build houses for people. When there’s more transportation materials like cars, the carbon dioxide and greenhouse gases are going to increase as well, causing global warming.
