These cases are rare, but what happens is something called an occluded front. There are so many things that could be talked about and results aren't typically constant, so I recommend you look up what an occluded front is. Its basically when a cold front catches up to a warm front and forces even more warm air up, causing high amounts of precipitation.
I there supposed to be a picture here or
Explanation:
It is given that,
Radius of the front sprockets, 
Radius of the rear sprockets, 
The angular speed of the front sprocket is 12.3 rad/s, 
(a) Linear speed of the front sprockets, 
Linear speed of the rear sprockets, 
(b) Let 
is the centripetal acceleration of the chain as it passes around the rear sprocket.
`Hence, this is the required solution.
Answer:
Friction force is the force that one object exerts in another when the two rub against each other. Most of the time, friction force opposes the motion of an object.
