If two wires run parallel and the current passes through both wires in the same direction, which happens to the wires?

If two wires run parallel and the current passes through both wires in the same direction, the wires wires move together because the current of one wire pulls the other wire closer. The answer is letter C.

A plane electromagnetic wave travels northward. At one instant, its electric field has a magnitude of 9.6 V/m and points eastwar
lara31 [8.8K]

Answer:

The values is  B  = 3.2 *10^{-8} \  T

The  direction is out of the plane

Explanation:

From the question we are told that

  The  magnitude of the electric field is  E  =  9.6 \  V/m

 

The  magnitude of the magnetic field is mathematically represented as

       B  = \frac{E}{c}

where c is the speed of light with value

      B  = \frac{ 9.6}{3.0 *10^{8}}

     B  = 3.2 *10^{-8} \  T

Given that the direction off the electromagnetic wave( c ) is  northward(y-plane ) and  the electric field(E) is eastward(x-plane ) then the magnetic field will be acting in the out of the page  (z-plane  )

Which team sport utilizes judges to determine the points earned? Football Hockey Rhythmic Gymnastics Soccer
finlep [7]

Answer:

Rhythmic Gymnastics

Explanation:

In general, the judges in the sports tend to be in charge for correcting and controlling the breaking of the rules in the particular sport. They are allowed to punish the competitors in accordance with the breaking of the rule, or they are there in order to determine weather a point is regular or not. In the rhythmic gymnastics though, and sports similar to it, the judges have different role, as they are in charge of determining the points earned by the competitors. This is done in a manner where every judge gives certain amount of points, or grades, and when those are summed up, the competitors get their total points.

What is the current in mA through a 500 Ω resistor that is connected to a 1.5 V battery? Show all calculations using Ohm’s law (
Ludmilka [50]

Answer:

3 mA.

Explanation:

The following data were obtained from the question:

Resistor (R) = 500 Ω

Potential difference (V) = 1.5 V

Current (I) =.?

Using the ohm's law equation, we can obtain the current as follow:

V = IR

1.5 = I x 500

Divide both side by 500

I = 1.5 / 500

I = 3×10¯³ A.

Therefore, the current in the circuit is 3×10¯³ A.

Finally, we shall convert 3×10¯³ A to milliampere (mA).

This can be obtained as follow:

Recall:

1 A = 1000 mA

Therefore,

3×10¯³ A = 3×10¯³ × 1000 = 3 mA

Therefore, 3×10¯³ A is equivalent to 3 mA.

Thus, the current in mA flowing through the circuit is 3 mA.
