Answer:
B. Newton's second law of motion
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass. 
Mathematically, it is given by the formula;
 
 
Making acceleration the subject of formula, we have;
 
 
In this scenario, the acceleration of a baseball after it is hit by a bat depends on the mass of the ball and the net force on the ball. Thus, this example best illustrates Newton's second law of motion.

Answer:
E=hf 
Were, h = Planck constant 6.67*10^11
E=3.8*10^24 * 6.67*10^11= 2.508*q0^36j
 
        
             
        
        
        
The words "... as shown ..." tell us that there's a picture that goes along 
with this question, and you decided not to share it.  That's sad and 
disappointing, but I think the question can be answered without seeing 
the picture.
The net force on the crate is zero.  Evidence for this is that fact that 
the crate is just sitting there.  If the net force on an object is not zero, 
then the object is accelerating ... it's either speeding up, slowing down, 
or its the direction of its motion is changing.  If none of these things is 
happening, then the net force on the object must be zero.
        
             
        
        
        
<em>An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge. Consider how a positive ion can form from an atom. The left side of the illustration below represents a sodium (Na) atom</em>
