Answer:
3 x 10^5  J
Explanation:
mass of substance, m = 1 g = 0.001 kg 
Velocity of light, c = 3 x 10^8 m/s 
According to the Einstein mass energy equivalence, the energy associated with the mass is given by 
E = m c^2 
E = 0.001 x 3 x 10^8
E = 3 x 10^5  J
 
        
             
        
        
        
The image will form in the vicinity of F. Its nature will be small and inverted 
        
                    
             
        
        
        
Hello!

Use the equation for momentum:

Plug in the given mass and velocity into the equation:

Explanation:
formula for energy is k. e = ½mv²
m= 9
v= 75 
k. e = ½×9×75 =337•5
