Which of the following choices concerning the net magnetic flux through any enclosed surface is true according to Gauss' law for
11Alexandr11 [23.1K]

Answer:

e. The net magnetic flux in this case would be equal to zero.

Explanation:

As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop

here we know that net magnetic flux is the scalar product of magnetic field vector and area vector

so here we have

\int B. dA = net magnetic flux

since we know that magnetic field always forms closed loop so if we find the integral over a closed loop

then in that case the value of the close integral must be zero

so correct answer would be

e. The net magnetic flux in this case would be equal to zero.

The core of the Sun is Group of answer choices
kap26 [50]

Answer:

2. much hotter and much denser than its surface

Explanation:

We know that the temperature around the center of the Sun is about 1.57×10⁷ K and its density is about 162 g/cm³.

Now, the temperature and the density decrease as one moves outward from the center of the Sun, the temperature at the surface of the sun is about 5×10³ K and the density as an average in the surface is about 1.4 g/cm³.

Therefore the answer is:

2. much hotter and much denser than its surface.  

I hope it helps you!

Have a nice day!
