Answer:

$BC = 8 \sqrt{2}$

Step-by-step explanation:

$\sin(45) = \frac{opposite}{hypotenuse}$

$\sin(45) = \frac{8}{BC}$

$(BC) \sin(45) = \frac{8}{x} (BC)$

$(BC) \sin(45) = 8$

$\frac{(BC) \sin(45) }{ \sin(45) } = \frac{8}{ \sin(45) }$

$BC = \frac{8}{ \sin(45) }$

$BC = 8 \sqrt{2}$

The Answer is F.

20min - 30min is -10 so you can take it out of 8h which will leave you with 7h and 50 minutes then
7h and 50 min minus 10 h is -3 h and 50 minutes take it out of the 7 day’s which leaves you with 6days and 24 h minus 3 h that it 6days and 21 h and 50 minutes in total and minus the ram aiming 4 days which will be

<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.
