An example of that would be if you were in space; you float around because there's no gravity.
 
        
             
        
        
        
Answer: The answer is 3000 K and Centauri A.
Explanation:
Just did it and got it right ♡´・ᴗ・`♡
 
        
                    
             
        
        
        
We have: Gravitational Potential Energy (U) = mgh
Here, m = 3 Kg
g = 9.8 m/s²        [ constant value for earth system ]
h = 3 m
Substitute their values into the expression:
U = 3 × 9.8 × 3
U = 88.2 J
In short, Your Answer would be 88.2 Joules
