Source of magnetic force - Nail

Source electric force - battery cell

<h3>What is an electromagnet?</h3>

We know that the electromagnet is a type of magnet whose magnetic property depends on the interaction of the magnetic material with an electric field. We can see in the image that the nail which serves as the magnetic material is connected to a cell which is the source of the given electric current.

It the follows that the nail above is the source of the magnetic force because the coils of wire while the battery cell is the source of the electrical force.

Name the missing coordinate(s) of each triangle
Cloud [144]

Answer:

13) C (a, a)  Y (a, 0)

14) B (0, b)  P (a, 0)

Step-by-step explanation:

13) Y lies on x axis so it is Y(a,0)

ZY = YC = a

so for C coordinates are (ZY,YC) = (a, a)

14) B lies on y axis so it is B(0, b)

BK = BP = \sqrt{a^{2} + b^{2}  } = distance between two points

so P is (a, 0) as it is same distance and on positive side of x axis

Given quadrilateral EFGH at e(-4,7) f(8,4) G(t,-5) and h(-7,-1) using coordinate geometry prove EFGH is a rectangle
Tcecarenko [31]

The above question was not properly written.

Complete Question

Given quadrilateral EFGH with vertices at E(-4,8), F(8,4), G(5,-5) and H(-7,-1), prove using coordinate geometry that EFGH is a rectangle.

Answer:

Quadrilateral EFGH is a rectangle.l because:

EF = GH and FG = EH

Step-by-step explanation:

The formula for coordinate geometry is given as :

√(x2 - x1)² + (y2 - y1)² when we have coordinates: (x1, y1) and (x2 , y2)

For the quadrilateral EFGH with given coordinates above to be a rectangle,

EF = GH

FG = EH

Hence:

For side EF

E(-4,8), F(8,4)

= √(8 - (-4))² + (4 - 8)²

= √12² + -4²

= √144 + 16

= √160 units

For side FG

F(8,4), G(5,-5)

=√(5 - 8)² + (-5 - 4)²

= √-3² + -9²

= √9 + 81

= √90 units

For Side GH

G(5,-5) , H(-7,-1)

= √(-7 - 5)² + (-1 - (-5))²

= √-12² + 4²

= √144 + 16

= √160 units

For side EH

E(-4,8), H(-7,-1)

= √(-7 -(-4))² +(-1 - 8)²

= √-3² + -9²

= √9 + 81

= √90 units

From the above calculation, we can see that truly,

EF = GH

FG = EH

Therefore, quadrilateral EFGH is a rectangle.

Darina [25.2K]

Answer:

Marisol is incorrct Diego and Andrea paid the same amount for each ticket . This is because 46.5 times 3 equals to 139.50 so each ticket cost the same amount of money.Since Andrea paid for 9 tickets and Diego for 3 you multiply the cost by 3 so you get the answer and see if its less or greater than Andreas aount of money.
