A current of 6.93 A 6.93 A in a long, straight wire produces a magnetic field of 4.15 μT 4.15 μT at a certain distance from the

natka813 [3]

Answer:

0.334 m

Explanation:

The magnetic field due to current in a straight thin wire, $B$ , is given by

$B = \dfrac{\mu_0 I}{2\pi R}$

where $\mu_0$ is the permeability of free spave with value $4\pi\times10^{-7}$ and $R$ is the distance from the wire.

$R = \dfrac{\mu_0 I}{2\pi B}$

Substituting the values from the question,

$R = \dfrac{4\pi\times10^{-7}\times 6.93}{2\pi\times 4.15\times 10^{-6}}$

$R = \dfrac{2\times10^{-1}\times6.93}{4.15} = 0.334 \text{ m}$

Maybe nobody ever mentioned it to you, but it turns out that
current is another one of those things that's always conserved ...
it can't created or destroyed, just like energy and mass.

The total current in a circuit is always the same, but it can get
split up and travel through different paths for a while.

==> The total current is just the amount of current
 that's flowing in and out of the battery.

Diagram #1).
The total current coming out of the battery is 15 A.
That current is going to split up when it reaches the resistors.
 Part of it will flow through each resistor, but both of them
 will still add up to 15 A .
You have 9 A flowing through one resistor.
So the current in the other resistor is (15 - 9) = 6 A.

Diagram #2).
The total current coming out of the battery is 10 A.
That current is going to split up when it reaches the resistors.
 Part of it will flow through each resistor, but all of them
 will still add up to 10 A .
You have 2.5 A through one resistor and 3.5 A through another one.
So the amount left for the last resistor is (10 - 2.5 - 3.5) = 4 A.

The Skeleton does a surprising number of things. What are the three main Ones? lol, it's due today at 12:59 pm I need help.

ICE Princess25 [194]

Answer:

Support

Posture

Protection

Explanation:

Support – the skeleton keeps the body upright and provides a framework for muscle and tissue attachment.

Posture – the skeleton gives the correct shape to our body.

Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact.
