Answer:</h3>
 117.6 Joules 
<h3>
Explanation:</h3>
<u>We are given;</u>
- Force of the dog is 24 N 
- Distance upward is 4.9 m 
We are required to calculate the work done
- Work done is the product of force and distance 
- That is; Work done = Force × distance
- It is measured in Joules.
In this case;
Force applied is equivalent to the weight of the dog.
Work done = 24 N × 4.9 m 
                   = 117.6 Joules 
Hence, the work done in lifting the dog is 117.6 Joules
 
        
        
        
An object that's moving doesn't necessarily change its speed or acceleration. Also, the force applied to it doesn't need to change ... in fact, a moving object doesn't need ANY force applied to it in order to keep moving.
But any moving object WILL have a change in its position ... THAT's how you know it's moving, and that's WHY you say "It's moving !". (choice-B) 
 
        
             
        
        
        
It will be unaffected by the magnet because it has no magnetic field. If you were to maybe have electricity going through it is the only way it would have anything to do with the magnet.
