 liquid, solid, and gas. A heating curve shows how the temperature changes as a substance is heated up at a constant rate.
Explanation:
 
        
             
        
        
        
The electrostatic force between two charges is inversely 
proportional to the square of the distance between them.
So if you want to multiply the force by, say, ' Q ', 
you need to multiply the distance by  ( 1 / √Q ) .
We want to multiply the force by 16, so we need to
multiply the distance by    ( 1 / √16 )  =  ( 1 / 4 ) .
The distance should be changed to  1/4  of what it is now.

Explanation:
The reading on the scale is
W = m(g + a)
 = (77 kg)(9.8 m/s^2 + 2 m/s^2)
 = 908.6 N
