Which best explains how Selena can correct her error? She can change the magnets so like poles are facing each other. She can ch

alexandr402 [8]

Complete question is;

Selena drew a diagram to show how current moves in a loop of wire that is placed between two magnets. At top left a piece of magnet labeled N and at top right a piece labeled S. Between these a square coil of wire with green arrows at its ends away from the magnets pointing away from the magnets. Red arrows point from N to S. Which best explains how Selena can correct her error?

A) She can change the magnets so like poles are facing each other.

B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.

C) She can change the arrows so they show the magnetic field reversing direction between the magnets.

D) She can change the magnetic poles so they are both on one side of the loop.

Answer:

B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.

Explanation:

Since the direction of the arrows point north and south whereas the magnets are east and west, it means the arrows are not pointing in the correct direction. To correct it she will have to make sure the arrows are pointing in opposite directions of the magnet via the sides of the loop.

Answer:

$x^2\neq -\frac{5}{13}$

First option

Explanation:

<u>Operations with functions </u>

Given two functions f, g, we can perform a number of operations with them including addition, subtraction, product, division, composition, and many others .

We have

$f(x)=20x^3-7x^2+3x-7$

$g(x)=-13x^2-5$

We are required to find

$\displaystyle \frac{f}{g}(x)$

We simply divide f by g as follows

$\displaystyle \frac{f}{g}(x)=\frac{20x^3-7x^2+3x-7}{-13x^2-5}$

We know rational functions may have problems if the denominator can be zero for some values of x. We must find out if there are such values and exclude them from the domain of the new-found function. We must ensure

$-13x^2-5\neq 0$

or equivalently

$x^2\neq -\frac{5}{13}$

Thus the first option is correct

Note: Since $x^2$ is always a positive number (for x real), our function does not really have any restriction in its domain

When drawing Lewis structures for simple molecules, you need to first sum the number of valence electrons from all atoms in the

timama [110]

Omg I love Lewis structures!

You have to first identify the central atom. In this case the central atom is Carbon, and it's surrounded by two oxygen atoms.
Carbon has 4 valence electrons. Oxygen has 6 valence electrons. it will have two double bonds.
I'll take a pic of it.
