hello brilliant student please help me to find the answer of this question please answer it fast I have to complete it
Answers
The answers are as follow:
1.highly polished surfaces — because in this friction force is low and in the other two options, it is high
2.sand — because other three options decrease the friction force but sand increases the friction
3.birds — because only birds are the natural living things but the other options are made artificially for transportation
Hope this will help u.....
1 . Friction is formed by 2 forces - deformation and adhesion ,therefore highly polished surface is the odd one out as it has the least friction.
2. Here graphite powder is nearly frictionless , therefore it is the odd one out
, And all other options create friction.
3. Need more details
My answer might not be correct but might be helpful, I would prefer you refer to smarter answers
