Answer:
(a) 2
Explanation:
Two points will define a ray. One of them is the end point. The other defines the direction of the ray.
__
Any line segment, ray, or line will consist of an infinite number of points. In each of these cases, 2 points is sufficient to define it.
It'd be D because twice the radius(16)would be the length of one side(32) and area for a square is side times side so it would be 1,024 ft^2
Hope that helped
I think the change in apparent position of the big dipper answer is revolving for 6 months
The distance that created from the revolving actually determine the earth's temperature and climate
hope this helps
Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
