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>

Answer: Islands
Explanation:
Some Islands like Hawaii and Japan were not original part of the super constant like other places, they were formed from volcanic rock and lava over time, from under the water. And became islands.

Explained
Explanation:
Answer: Of the list following are
Arkose, chert, limestone, breccia, shale, dolostone sedimentary rocks. Don't confuse dolostone with dolomite- the latter is a metamorphic rock.
Why other options are wrong:
Hornfels, quartzite ,Amphibolite and Phyllite are metamorphic rocks
Gabbro is a igneous rock.
Answer:
Explanation:
To rank these foods in the amount of sugars, I will first explain the index I will use, which is called the glycemic index. This index is based on the classification of carbohydrate-rich foods according to how they affect blood glucose levels, popularly known as blood sugar.
The higher the glycemic index, the easier the food is digested and absorbed in the gut, increasing the glycemia. Thus, the foods were divided into 3 categories:
Low IG: 55 or less
Average IG: 56 - 69
High IG: 70 or more
Based on this, the lowest to highest glycemic level food ranks as follows: beans, liver, carrots, white rice and baked potatoes.
