An interaction between two charged particles may give off energy. This interaction between them is called magnetism and that the force that is created is referred to as magnetic force or more specifically, electromagnetic force. The equation that best deals with this type of interaction is incorporated in Coulomb's law.
Answer:
The new angular speed is
Explanation:
From the question we are told that
The angular velocity of the spin is
The original moment of inertia is
The new moment of inertia is
Generally angular momentum is mathematically represented as
Now according to the law of conservation of momentum, the initial momentum is equal to the final momentum hence the angular momentum is constant so
=>
where w is the new angular speed
So
=>
=>

Answer:
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
Resistor X is the same material and thickness as resistor Y, but it is twice as long. The resistance of resistor X is double that of resistor Y.Option 2 is correct.
<h3>What is resistance?</h3>
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The relation of the resistance with the length and thickness is;
For the given case;
Resistor X has the same thickness and is made of the same material as resistor Y but has twice the length. Resistor X has twice the resistance of resistor Y.
Hence,option 2 is correct.
