A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. The endpoint of a ray is point S. The correct option is B.
<h3>What is a ray?</h3>
A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. It is assumed to be infinite.
Given that Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T.
Also, A third line extends right and up from point S through point U. This can be drawn as shown below.
Now, since all the ray starts from point S, therefore, the endpoint of a ray is point S.

Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
I think the answer is A good luck
<span>It must measure the supergranules. This refers to the physical pattern casing the exterior of the quiet Sun with an archetypal horizontal scale of approximately 30,000 km and a lifetime of around 1.8 d. Its most noticeable or visible signature is as a fluctuating velocity field of 360 m st-1 rms whose components are mostly horizontal. This was exposed more than fifty years ago, conversely clearing up why and how it originates still represents one of the core challenges of modern solar physics.</span>
The correct answer is false.
