D
Explanation:
correct me if I'm wrong on your answer and it's the right answer from my son
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.

See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
Answer:
Average speed is 14 m/s and average velocity is 10 m/s.
Explanation:
The time consumed to travel from A to B = Distance / Speed = 30 / 10 = 3 seconds
The time consumed to travel from B to C = Distance / Speed = 40 / 20 = 2 seconds
Now, we find the average speed by using the below formula.
Average speed = total distance / total time
Average speed = (30 +40) / (3 + 2)
Avergae speed = 70 / 5 = 14 m/s.
Now find the average velocity.
Average velocity = displacement / time
Displacement, distance between A to C = [(30)^2 + (40)^2]^1/2 = 50 m
Average velocity = 50 / (3+2) = 10 m/s
