Answer: Newton, the unit of force, is defined based on Newton's Second Law (F=ma), as the force required to give a mass of one kilogram an acceleration of 1 meter/second2. Thus, it is derived from these other units.

Speed of light 
According to Einstein, the speed of light is constant in all points of reference.  In addition, he pointed out the speed of light is the maximum speed known since in practice one can never catch up with the beam of light. This is explained by his theory of relativity. 
        
                    
             
        
        
        
I think it would be warmer in a grassy field with no wind on a winter day because you'll have sunlight hitting you.

Kinetic Energy would have to be the answer. Pretty sure.
        
             
        
        
        
The correct answer is the third one: move toward the ground state. Remember please that Elements produce their spectrum when their electrons move toward the ground state. Hope this is very useful
