Answer:
The answer to your question is a = 0.25 m/s²
Explanation:
Data
mass = m = 400 kg
Force = F = 100 N
acceleration = a = ? m/s²
Process 
To solve this problem use Newton's second law that states that the force applied to an object is directly proportional to the mass of the body times its acceleration.
Formula 
                        F = ma
solve for a
                        a = 
Substitution
                        
Simplification and result
                               a = 0.25 m/s²
 
        
             
        
        
        
Answer: The pressure that one experiences on the Mount Everest will be different from the one, in a classroom. It is because pressure and height are inversely proportional to each other. This means that as we move up, the height keeps on increasing but the pressure will keep on decreasing. This is the case that will be observed when one stands on the Mount Everest as the pressure is comparatively much lower there.
It is because as we move up, the amount of air molecules keeps on decreasing but all of the air molecules are concentrated on the lower part of the atmosphere or on the earth's surface.
Thus a person in a low altitude inside a classroom will experience high pressure and a person standing on the Mount Everest will experience low pressure.
 
        
             
        
        
        
The plant will not grow. In fact it could have all the nutrients and all the water it needs, but without a sufficient amount of light, it could die because its leaves are meant for a certain minimum amount of light.

Answer:
The formula is dimensionally correct.
Explanation:
Given

Required
Prove its correctness
Write out the dimension of each:
 --- displacement
 --- displacement
 --- velocity * time
 --- velocity * time
 --- acceleration * square of time
 --- acceleration * square of time
The expression becomes:


Apply law of indices



Both sides of the equation are equal
