It must gain an electron because if the proton number was to change it would no longer be the same element.
        
             
        
        
        
Answer:
96w
Explanation:
p=Iv..where v=12 and I=8.0
 
        
             
        
        
        
D.) Distance travelled / time ...........
        
             
        
        
        
I think D x=vxt because it's equation finding change of x (displacement) and using time
        
             
        
        
        
Hope it helped you.
A. Acceleration is a wrong answer. Acceleration is the rate of change to in velocity. It involves a change in speed and direction. 
B.  Force is a wrong answer. Force is a directions from push/or pull.
C. Inertia is a correct. Inertia is a tendency of an object to stay at the rest or preserve its state of motion.
D. Velocity is a incorrect answer. Velocity is the placement of an object during a specific unit of time. It has two measurements are needed to determine velocity.
