Answer:

The distance will be "0.319 m".

Explanation:

The diagram of the given question is not attached with the problem. Below is the attached figure.

The given values are:

$q1 = -3.33\times 10^{-9} \C$

$q2 = -5.22\times 10^{-9} \ C$

As we know,

The electric field will be equivalent as well as opposite throughout the direction, then

⇒ $\frac{R.q1}{(0.255)^2} =\frac{R.q2}{r^2}$

⇒ $r^2=\frac{q2}{q1}\times (0.255)^2$

By putting the values, we get

⇒ $=\frac{-5.22\times 10^{-9}}{-3.33\times 10^{-9}}\times (0.255)^2$

⇒ $=1.568\times 0.065$

⇒ $r^2=0.10193$

⇒ $r=\sqrt{0.10193}$

⇒ $0.319 \ m$

Two long, straight wires are parallel and are separated by a distance of d = 0.210 m. The top wire in the sketch carries current

Answer:

$1.88\cdot 10^{-5} T$ , inside the plane

Explanation:

We need to calculate the magnitude and direction of the magnetic field produced by each wire first, using the formula

$B=\frac{\mu_0 I}{2\pi r}$

where

$\mu_0$ is the vacuum permeability

I is the current

r is the distance from the wire

For the top wire,

I = 4.00 A

r = d/2 = 0.105 m (since we are evaluating the field half-way between the two wires)

$B_1 = \frac{(4\pi\cdot 10^{-7})(4.00)}{2\pi(0.105)}=7.6\cdot 10^{-6}T$

And using the right-hand rule (thumb in the same direction as the current (to the right), other fingers wrapped around the thumb indicating the direction of the magnetic field lines), we find that the direction of the field lines at point P is inside the plane

For the bottom wire,

I = 5.90 A

r = 0.105 m

$B_2 = \frac{(4\pi\cdot 10^{-7})(5.90)}{2\pi(0.105)}=1.12\cdot 10^{-5}T$

And using the right-hand rule (thumb in the same direction as the current (to the left), other fingers wrapped around the thumb indicating the direction of the magnetic field lines), we find that the direction of the field lines at point P is also inside the plane

So both field add together at point P, and the magnitude of the resultant field is:

$B=B_1+B_2 = 7.6\cdot 10^{-6} T+1.12\cdot 10^{-5}T=1.88\cdot 10^{-5} T$

And the direction is inside the plane.

What is climate change? How is it caused

OleMash [197]

climate change is a change in climate in the Earth 's normal weather patterns for different climates. it normally changes little by little over the years.the earth is cooler and warming .now it's getting warmer. this phenomenon is also known by as globall warming.it's causes are:

1.energy uses

2.agriculture and land use 3.Transport 4.Industries 5.Growing demands for food and water

A greenhouses is made from glass or clear plastic. It is useful for growing plants in winter in cooler climates.

How do determine which is Y2, Y1, X2, and X1 on a graph. <br><br> And how do find rise over run.

fredd [130]

One point will be X1,Y1 and the other will be X2,Y2. It does not matter which is which except that X1 and Y1 have to be the same point and X2 and Y2 have to be the same point. For example, let's say you were given (2,3) and (6,8). No matter which point is X1,Y1 and the other is X2,Y2, the slope will still be 5/4.

The rise is the change in y from one point to the other. The run would be the change in x from one point to the other.
