Answer:

30 V

Step-by-step explanation:

The induced emf, ε = -ΔΦ/Δt where  ΔΦ = change in magnetic flux and  Δt = time interval for change in flux.

Since we have N₂ = number of turns on second coil = 12 and initial flux per turn = 1.9 Wb per turn. The total initial flux per turn Φ₁ = 12 turns × 1.9 Wb per turn =  22.8 Wb.

Also, since we have N₂ = number of turns on second coil = 12 and final flux per turn = 2.4 Wb per turn. The total initial flux per turn Φ₂ = 12 turns × 2.4 Wb per turn =  28.8 Wb.

Since  Δt = 0.2 s and the magnitude of the induced emf in the second coil, ε = ΔΦ/Δt

= (Φ₂ - Φ₁)/Δt

= (28.8 Wb - 22.8 Wb)/0.2 s

= 6.0 Wb/0.2 s

= 30 V

option C

Step-by-step explanation:

got it right on edge 2020

The expression Z₁ -Z₂ is 4 - (4√3 -16)i.

Subtraction is mathematic operation. Which is used to remove terms or objects in expression.

The given expression Z₁ = 4 - 4√3i.

And Z₂ = -16i

Subtract Z₂ to Z₁:

Z₁ -Z₂

=  4 - 4√3i - (-16i)

=  4 - (4√3 -16)i.

Therefore,  Z₁ -Z₂ is 4 - (4√3 -16)i.

Answer:

The greatest common factor of 128 and 192 is 64, because 64 is the highest number that is divisible by both numbers.

The greatest common factor of 128 and 192 is 64 because 64 is the highest number that is divisible by both numbers.

The greatest common factor is the largest positive number which can be divided into given numbers evenly.

In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.

Given that the two numbers are 128 and 192. The greatest common factor is the largest number which is divided into both numbers.

128 = 2 x 2 x 2 x 2 x 2 x 2 x 2

192 = 2 x 2 x 2 x 2 x 2 x 2 x 3

The greatest common factor is,

GCF =  2 x 2 x 2 x 2 x 2 x 2

GCF = 64

Answer:

5,2

Step-by-step explanation:

Clockwise rotations for 90 is

The preimage of (x,y), or for this problem, (-2,5) into (y,-x).

So, a clockwise rotation is from x,y into y,-x

So we do -2,5 into 5,2

We flipped the x and y, and the 2 became positive because two negatives equal a positive

When a point is rotated, it must be rotated through a point.

The image of P is: (5,2)

The point is given as:

[tex]\mathbf{P = (-2,5)}[/tex]

The rule of 90 degrees clockwise rotation is:

[tex]\mathbf{(x, y) \to (y, -x)}[/tex]

So, we have:

[tex]\mathbf{(-2, 5) \to (5, 2)}[/tex]

This gives:

[tex]\mathbf{P' = (5, 2)}[/tex]

Hence, the image of P is: (5,2)

Answer:slope = -2/3

Y inter. =7

Step-by-step explanation:

To get the slope= y-y divide x-x which is = 3-5 divide 6-3

= -2/3

So the equation will be :

Y=mx+b

Y=-2/3x+b

Now to get the b which is the yinter. We have to put a “x” and a “y “

Lets put (3,5)

5=-2/3 x (3) +b

5= -2 + b

7=b
