Two boys are riding their bicycle on the same concrete road one has new tyres on his bicycle while the other has tyres that are old and used which of them is more likely to skid while moving through a patch of the road which has lubricating oil spills over it
Answers
Answer:
The boy with old tyres .
Concept : Friction
Explanation:
According to the question there are two boys riding bicycle ( say X and Y ) . X has new tyres in his bicycle and Y has old and used tyres in his bicycle . New tyres have better grip than old ones and as they are not used they are more firm to road because of new grip and in used tyres the grip is not good and the tyres are worn out , So frictional force will act more on X's bicycle and less on Y's bicycle
Hence the one who has old and used tyres is more likely to skid
Answer:
The bicycle with worn out tyres is more likely to skid.
Explanation:
A new tyre's surface is made in such a way that there is sufficient friction between the tyre and the road. As the tyre is used, wear and tear happens in the tyre and the surface of the tyre smoothens thereby reducing friction between the tyre and road. So it is more likely to skid.
