I THINK C BECAUSE IF IT IS A GLASS BOX HOW DID A CACTUS GET IN AND NOTHING CAN GET IN OR OUT OF THE BOX SO THERE IS NO CACTUS IN THE BOX
        
                    
             
        
        
        
By definition we have to:
 Applied force: It is the external force that acts directly on a body.
 Therefore, we can say that if you have an object and push it towards yourself, you are exerting an external force on the object.
 This external force was not acting on the object previously, therefore, it is a force that you are applying at that moment.
 Answer:
 you exert an Applied Force on an object when you pull it towards you

Answer:

Explanation:
Given 

r=2cm 
Now angular velocity is given by 

Now linear velocity(v) is given =

Now tangential component of acceleration is given by 

at t=0

radial component of acceleration is given by 



at t=0
