D. circles around the wire that go in at the bottom

Explanation:

In order to determine the direction of the magnetic field around the wire, we should use the right's hand rule. First of all, let's keep in mind that the magnetic field around a current carrying wire consists of concentric circles around the wire, so the only possible options are C and D.

In the right-hand rule, we put our thumb in the same direction of the current (so, toward the right). Then we wrap all the other fingers of the hand around the thumb: the direction of the fingers give the direction of the magnetic field. In this case, the fingers go in at the bottom of the thumb (bottom of the wire), so the correct option is

D. circles around the wire that go in at the bottom

In urgent need of help, science is my worse subject!
taurus [48]

The first reason is that in the past humans didn't necessarily see the connections between the oceans and thus labelled them that way separating them into 5 oceans and the names stuck to this day.

Secondly, while all the oceans of the world constitute one large Ocean, people need some way to identify each part of it since it is easier to think when we have different categories instead of one large category.

Hope that helped!

58.5 million excess electrons are inside a closed surface. What is the net electric flux through the surface?
Anni [7]
The biggest thing you're doing wrong is ignoring the units
when you're working with the quantities.

Now let's look at the rest of the problem:

The formula you used is correct:

           Net flux through the surface = (net charge inside) / ε₀

and          ε₀ = 8.85 x 10⁻¹² farad/meter.

What's the net charge inside the surface in this problem ?

It's    (5.85 x 10⁷ electrons) x (the charge on each electron)

     =  (5.85 x 10⁷ electrons) x (-1.6 x 10⁻¹⁹ coulomb/electron)

     =      -9.36 x 10⁻¹² coulomb .   

Finally,      (net charge inside) / ε₀

             =  (-9.36 x 10⁻¹² coulomb) / (8.85 x 10⁻¹² farad/meter)

             =        -1.058  newton-m²/coulomb .

The sign and the significant figures in your answer are correct, so
we can see that you know what you're doing.  The only thing left is
the order of magnitude.  You most likely took one of the negative
exponents and made it positive.  You got an answer that's 10²² too
small.  Big deal.  You could claim "that's close", and see whether you
can convince a teacher.

Shtirlitz [24]
Maybe, but she hasn't proved it yet. As another example, somebody may bring a jar of gas to your laboratory, and you test the gas in the jar and you find nitrogen atoms, oxygen atoms, argon atoms, and krypton atoms, and there isn't a single compound in it. The gas in the jar is a MIXTURE of gases . . . a mixture that we call "Air".
