red goes to red, black goes to white, yellow goes to green, blue goes to blue.
Answer:
the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.
Answer: Option (b) is the correct answer.
Explanation:
According to ohm's law, the relationship between voltage, resistance, and current is that current passing through a conductor is directly proportional to the voltage over resistance.
Mathematically, I = ![\frac{V}{R}](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BR%7D)
From this relationship we can see that when we decrease the voltage, and do not change the resistance, the current will also decrease. As current is directly proportional to voltage and inversely proportional to resistance.
Answer:
The values is ![B = 3.2 *10^{-8} \ T](https://tex.z-dn.net/?f=B%20%20%3D%203.2%20%2A10%5E%7B-8%7D%20%5C%20%20T)
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](https://tex.z-dn.net/?f=E%20%20%3D%20%209.6%20%5C%20%20V%2Fm)
The magnitude of the magnetic field is mathematically represented as
![B = \frac{E}{c}](https://tex.z-dn.net/?f=B%20%20%3D%20%5Cfrac%7BE%7D%7Bc%7D)
where c is the speed of light with value
![B = \frac{ 9.6}{3.0 *10^{8}}](https://tex.z-dn.net/?f=B%20%20%3D%20%5Cfrac%7B%209.6%7D%7B3.0%20%2A10%5E%7B8%7D%7D)
![B = 3.2 *10^{-8} \ T](https://tex.z-dn.net/?f=B%20%20%3D%203.2%20%2A10%5E%7B-8%7D%20%5C%20%20T)
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 )
