Answer:
1.It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
2.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
3.In nuclear reactions, mass is never conserved—some mass is exchanged for energy and energy for mass. Nuclear reactions take place in an atom's nucleus. In a spontaneous nuclear reaction, such as radioactive decay, mass is "lost" and appears as energy in the form of particles or gamma rays.
4.In a nuclear reaction, mass decreases and energy increases. The sum of mass and energy is always conserved in a nuclear reaction.
5.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

This is a Physics question where we need to figure out how many meters Cam can run per second. To figure this out we divide the distance by the change in time.
40/5.79 = 6.9 meters per second approximately.
 
        
                    
             
        
        
        
Yes, of course, a good example would be us.
        
                    
             
        
        
        
Answer:
the final velocity of the cart is 30 m/s
Explanation:
Given;
initial velocity of the cart, u = 10 m/s
distance moved by the cart, d = 200 m
acceleration of the cart, a = 2.0 m/s²
The final velocity of the cart is calculated as;
v² = u² + 2ad
where;
v is the final velocity
v²  = 10² + 2(2)(200)
v² = 900
v = √900
v = 30 m/s
Therefore, the final velocity of the cart is 30 m/s
