Explain using Newton's third law of motion

Click For Summary
Newton's third law of motion states that for every action, there is an equal and opposite reaction. On an icy surface, a car's tires cannot generate sufficient friction to push against the ground, preventing effective acceleration regardless of engine strength. Conversely, on a rough dirt surface, a vehicle can push a lighter car from rest, allowing it to accelerate due to better traction. The discussion highlights the importance of friction in motion and how it affects a vehicle's ability to accelerate. Understanding these principles is crucial for analyzing vehicle performance in different conditions.

1. no matter how strong a car engine is a car cannot accelerate on an icy surface
2. A vehicle pushes a car of lesser mass from rest, causing the car to accelerate on rough dirt.

Can you accelerate on icy surface?
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
