Why do sunspots appear dark in pictures of the Sun?

1 answer:

5 0

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.

All forms of electromagnetic radiation occur as waves.<br> true<br> false

Liula [17]

I believe it is false.
I think that electromagnetic radiation can occur in other forms such as rays. Rays and waves seem similar and are both apart of the electromagnetic spectrum, but they take different forms.

The function f is continuous on the interval (0,16), and f is twice differentiable except at x=5 where the derivatives are undef

Oliga [24]

Using it's definition, it is found that the function f(x) has a point of inflection at:

A. x = 8 only.

<h3>What are the points of inflection of a function?</h3>

The critical points of a function are the <u>values of x</u> for which:

$f^{\prime\prime}(x) = 0$

Additionally, there has to be a change in the sign of $f^{\prime\prime}(x)$

Researching the problem on the internet, it is found that:

For 0 < x < 5, $f^{\prime\prime}(x) > 0$ .

For x = 5, $f^{\prime\prime}(x)$ is undefined.

For 5 < x < 8, $f^{\prime\prime}(x) < 0$ .

For x = 8, $f^{\prime\prime}(x) = 0$ .

For 8 < x < 12, $f^{\prime\prime}(x) > 0$ .

For x = 12, $f^{\prime\prime}(x) = 0$ .

For 12 < x < 16, $f^{\prime\prime}(x) > 0$ .

The two conditions, $f^{\prime\prime}(x) = 0$ and a change in the signal of $f^{\prime\prime}(x)$ are only respected at x = 8, which is the lone inflection point.
