Answer:
No one is right
Explanation:
John Case:
The function  is defined between -1 and 1, So it is not possible obtain a value
 is defined between -1 and 1, So it is not possible obtain a value  greater.
 greater.  
In addition, if you  move the function cosine a T Value, and T is the Period,  the function take the same value due to the cosine is a periodic function.
Larry case:
Is you have  , the domain of this is [0,2].
, the domain of this is [0,2].
it is equivalent to adding 1 to the domain of the  , and its mean that the function
, and its mean that the function  , in general, is not greater than
, in general, is not greater than  .

Answer : 413.44N 
Here it is given that an elevator is moving down with an acceleration of 3.36 m/s² . And we are interested in finding out the apparent weight of a 64.2 kg man . For the diagram refer to the attachment . 
- From the elevator's frame ( non inertial frame of reference) , we would have to think of a pseudo force. 
- The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame . 
- When a elevator accelerates down , the weight recorded is less than the actual weight .
From the Free body diagram ,
 
 
 
 
- Mass of the man = 64.2 kg
 
 
 
 
 
 
 
        
             
        
        
        
Answer:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. ... For example, natural gas plants have become increasingly more efficient, thus humans are able to obtain more energy out of the same amount of gas.
Rapid population growth is detrimental to achieving economic and social progress and to sustainable management of the natural resource base. But there remains a sizeable gap between the private and social interest in fertility reduction, and this gap needs to be narrowed.
 
        
             
        
        
        
I would say a short person with muscles considering they are closer to the ground, but they may not be able to build up as much force in such a short time compared to the tall person.
