I think its b because when there is unbalanced forces it accelerates.
Hope this helps you out
The work is being done in following cases:
A mover carries a box up a flight of stairs.
A mover carries a box across a room.
Wind blows a pool chair across the yard.
A weightlifter lifts a barbell off the ground.
These are the only cases in which work is being done. The Formula of Work is:
Work= Force applied x Distance moved.
In all of these cases force is being applied and the object on which the force is being applied move in a horizontal or Vertical direction. Thus Work is done !
The kinetic energy of an object is directly proportional to its mass, and to the square of its velocity.
Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse, 
tangential speed , 
Radius of salami is:
Thus, the radius of the salami is 0.09 m.
