Answer:
Balanced forces are equal and opposite forces that act on the same object. ... Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.
 
        
                    
             
        
        
        
The ability to reproduce is essential for a species, but not for an individual. There are some people that can't reproduce, but they're still alive!
        
             
        
        
        
Answer:
The speed after being pulled is 2.4123m/s
Explanation:
The work realize by the tension and the friction is equal to the change in the kinetic energy, so:
 (1)
 (1)
Where:

Because the work made by any force is equal to the multiplication of the force, the displacement and the cosine of the angle between them.
Additionally, the kinetic energy is equal to  , so if the initial velocity
, so if the initial velocity  is equal to zero, the initial kinetic energy
 is equal to zero, the initial kinetic energy  is equal to zero.
 is equal to zero.
Then, replacing the values on the equation and solving for  , we get:
, we get:


So, the speed after being pulled 3.2m is 2.4123 m/s
 
        
             
        
        
        
Answer:0.6kw
Explanation:
Power=force×velocity
Power=20×30=600w
In kw it's going to be 600/1000=0.6kw
