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.

Answer:
The answer is below
Explanation:
Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.
Total distance traveled = distance traveled north + distance traveled east + distance traveled south
Total distance traveled = 100 + 50 + 60 = 210 meters
Displacement is the shortest distance between the starting and end points.
displacement² = 50² + (100 - 60)²
displacement² = 2500 + 1600
displacement = 64 meters
The displacement of the journey is vector, because displacement is a vector quantity.
Answer:
voltage measured by the voltmeter = (E × RV)/(r + RV)
Explanation:
The circuit diagram for this description is presented in the attached image.
The internal resistance of an emf source is modelled to be in series with the source.
Therefore, the end product is a circuit with the battery in series connection with the internal resistance and resistance of the volunteer. The voltage picked up by the volunteer is the voltage across resistor RV.
Total resistance in the circuit = (r + RV) ohms (since both resistors are in parallel)
Current produced by the emf source = E/(Total resistance) = E/(r + RV)
The voltage across resistor RV = current flowing through this resistor × its resistance.
Since all the circuit elements are in series with each other, same current, E/(r + RV) flows through them all
Voltage across RV = voltage measured by the voltmeter = [E/(r + RV)] × RV = (E × RV)/(r + RV) = (E.RV)/(r + RV)
When is at the end of the runway the velocity of the plane is given by the equation
where s=1800 m is the runway length. Thus
At half runway the velocity of the plane is
Therefore at midpoint of runway the percentage of takeoff velocity is
