A circular coil lies flat on a horizontal surface. A bar magnet is held fixed above the center of the coil with its north pole pointing downward. What is the direction of the induced current in the coil

Answers

Answer 1

Answer:

Explanation:

If the magnet is dropped from this position, then the direction of the induced current in the coil would be anticlockwise. Lenz's law allows us to predict the direction of the induced current in a circuit. It is also known as the Right hand rule. It states that the current that is being induced in a particular circuit is as a result of the change in the magnetic field in order to oppose the change in the magnetic flux and also to apply an mechanical force that is opposing the motion. Because of this, the current is pointed to the direction of the pole, to oppose this the induced current should be directed anticlockwise.

Two objects have mass 8 kg and 25 kg. Which one has more inertia?""

Answers

Answer:

the 25 kg one

Explanation:

The higher the weight the higher the inertia.
lets suppose we blow wind at both of these objects at a very high rate equally, u will notice after some time depending on the strength of wind the 8kg object will probably move earlier than the 25 kg one.

Write the equation of the line that has an undefined slope and passes through the point (4, 7). User: What is the slope of a line that is parallel to the x-axis? User: What is the slope of the line that passes through the points (-3, 5) and (1, 7)? User: Which of the following equations is the translation 2 units left of the graph of y = |x|?

Answers

Answer:

$y = m(x - 4) + 7$

Explanation:

as we know that equation of straight line passing through a fixed point and having undefined slope is given as

$y - y_1 = m(x - x_1)$

here we have

$(x_1, y_1) = (4, 7)$

so we will have

$y - 7 = m(x - 4)$

$y = m(x - 4) + 7$

Answer:

slope = ZERO

Explanation:

Slope of the straight line is defined as the tangent of the angle made by the line with respect to x axis

here we need to find the slope of a straight line parallel to x axis so the angle is ZERO degree

hence the slope will be given as

$m = tan 0$

$m = 0$

Answer:

$m = 0.5$

Explanation:

Slope of a straight line passing through two different points is given as

$m = (y_2 - y_1)/(x_2 - x_1)$

here we will have

$m = (7 - 5)/(1 + 3)$

$m = (2)/(4)$

$m = 0.5$

Answer:

$y = |x - x'|$

here x' = any positive number

Explanation:

If we translate the graph 2 units left of the given position so we can say that we have shifted the graph above from its given position.

So we will have

$y = |x - x'|$

here x' = any positive number

For the first question we use point-slope form of an equation

y- $y_(1)$ =m(x- $x_(1)$ )
y=m(x- $x_(1)$ )+ $y_(1)$

then we plug in the known values

y=m(x-4)+7

we leave the slope as variable m since it is undefined

For Question 2

A line that is parallel to the x-axis is a horizontal line and since the slope of a line is defined as the Δy/Δx (change in y/change in x) and the change in y is 0 at any 2 points observed on the line the slope is 0. (0/any number is 0)

For Question 3

Following the same relationship as question 2 we can solve for the slope.

Δy/Δx
$y_(1)$ - $y _(2)$ / $x_(1)$ - $x_(2)$

now we plug in the known values from the two points given

(5-7)/(-3-1)
-2/-4
m=1/2 or 0.5

and For the Final Question

a translation left or right is done by affecting the x variable if you add 2 to x then the x value will have to be 2 less to get the same result...in other words when x is 1 the value of y is also 1...but if I wanted the whole equation translated left 2 unites then I would want the same y-value at an x-value 2 smaller... in other words, in our example x will be -1 when y is 1. For this value found on the graph to match the equation our x value must have 2 added to it in the equation....therefore the equation that translates y=|x| two units left is...

y=|x+2|
