Sunspots appear dark in pictures of the Sun as they actually are fairly bright but appear dark against the even brighter background of the surrounding Sun. Thus, the correct option for this question is A.
<h3>What are Sunspots?</h3>
Sunspots may be defined as areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun's surface. Solar flares are sudden explosions of energy caused by tangling, crossing, or reorganizing magnetic field lines near sunspots.
According to the context of this question, sunspots are blotches on the sun that appear dark because they are cooler than the rest of the solar surface.
Astronomers do know they are linked to intense magnetic activity on the sun, which can suppress the flow of hot matter, but much about their structure and behavior remains enigmatic.
Therefore, the correct option for this question is A.

Based on the information given regarding the angle of elevation and depression, the true statements are A, C, and D.
<h3>How to solve the angle of elevation and depression.</h3>
From the complete information, the first angle has legs 529m and 229m.
The second one has legs 529m and 347m. Therefore tan x will be = 529/229 = 2.31
Tan y will be = 529/347 = 1.52
It can be noted that tan x > tan y. There are two parallel lines given and angle x, v, y, and w are alternate angles.
Therefore, the correct options are A, C , and D.

An object is moving due north at 32m/s. then this tells about the velocity of the object as it has the direction.
<h3>What is the difference between velocity and speed?</h3>
The immediate velocity of an item is then the value of its immediate pace. Speed tells you the way rapid. Velocity tells you the way rapid and in what route.
When you realize each velocity and route of an item's motion, you realize the speed of the item. Velocity tells us the velocity and route of a shifting item. Acceleration tells us the charge at which the pace changes.
