Answer:
 
Explanation:
you mean deceleration right ? because the acceleration is 250m/s
 
        
             
        
        
        
Formula for potential energy is V=mgh, where m is mass in KG, g is earth acceleration (10 m/s^2), and h its height in meters. We know mass, acceleration is constant and also known, we know height also. Lets substitute
V=75*10*300=225000[J]=225[kJ] - its the answer
        
             
        
        
        
Explanation:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Answer:

Explanation:
The electrostatic potential energy is given by the following formula

Now, we will apply this formula to both cases:

So, the change in the potential energy is

 
        
             
        
        
        
Voltage = Current (I) × Resistance (R)
V = 10 × 28.5 = 285v
