Option (B)is correct.
Alternating electric and magnetic fields has electromagnetic radiation that travel in the form of a wave.
The varying or alternating electric field produces the varying magnetic field.This varying magnetic field in turn produces varying electric field . Thus these varying electric and magnetic fields travel in the form of electromagnetic waves. These electromagnetic waves travel with the velocity of light.These are transverse in nature.
Answer:
The ball will be attracted to the negatively charged plate. It'll touch and pick up some electrons from the plate so that the ball becomes negatively charged. Immediately the ball is repelled by the negative plate and is attracted to the positive plate. The ball gives up electrons to the positive plate so that it is positively charged and suddenly attracts to the negative plate again, flies over to it and picks up enough electrons to be repulsed by negative plate and again to the positive plate and that continues.
The answer would be a bicycle as it uses both wheels and an axel
<u>Answer:</u>
This figure shows the Second Kepler’s Law of Planetary Motion, <em>The line that joins the planet with the Sun sweeps equal areas in equal times</em>.
According to this statement, the only way in which this is fulfilled is that the planet moves faster when it is <u>near the sun (perihelion)</u> and moves slower when it is <u>far from the Sun (aphelion</u>).
In the image shown, if points W and X are at the same distance to the Sun, this means the instantaneous velocity of the planet in both points is the same.
Answer:
Dissociation- disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity.
Ionization- the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
