Answer:
D. the masses of the objects and the distance between them
Explanation:
Gravitation is a force, a force doesn't care about the shape or density of objects, only about their masses... and distances.
And you can get it using the following equation:

Where :
G is the universal gravitational constant
: G = 6.6726 x 10-11N-m2/kg2
m represent the mass of each of the two objects
d is the distance between the centers of the objects.
 
        
             
        
        
        
The presence of potential energy  between particles supports the shape of a heating curve.
<h2>Potential energy and heating curve</h2>
The existence of potential energy  between particles supports the shape of a heating curve because potential energy causes the heating curve flat as well as in curve form. The heating curves show how the temperature changes as a substance is heated up. 
The potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing so when the heating curve go flat it means there is potential energy so we can conclude that the existence of potential energy  between particles supports the shape of a heating curve.

Potential difference across the entire cd player is 12 V
        
             
        
        
        
Answer:
Explanation:
M = 1.989 x 10^30 kg 
R = 6.96 x 10^8 m 
G = 6.67 x 10^-11 Nm²/kg²
Let the velocity is v. 


v = 6.17 x 10^5 m/s
