Which of the following can be a disadvantage of frictions 1)it helps moving bodies to come to rest
2)it helps resting bodies to move
3)None of these
4)all of the above

It helps moving bodies come to rest

Explanation:

friction happens when 2 surfaces are sliding against eachother, friction usually goes in the opposite direction in which the object is moving

ex: if you slide a book across a desk, friction makes this hard or slow, therefore it comes to a stop faster.

All in all, friction would help a moving body come to rest or essentially "stop"
