Imagine you are in a swimming pool 30m deep. Assuming you know that water is denser than air, you would know that the 30m of water above you will carry more weight, and press down on your body. Say you were in a swimming pool 60m deep, you would be sandwiched between 30m of water pressing down on you, and the upthrust created by the 30m of water below you.
In a building 30m up, the pressure will be regulated, as you are in a building. The floor will be strong enough to support the weight of the body, and the body will not recoil into itself.
        
             
        
        
        
Answer:
The internet is most useful to them because they use it to communicate.

On the other hand if I were going to meet him and then explain what I wanted to tell him in person it would take a much longer time.

Acceleration  is expressed in the following formula:
 is expressed in the following formula:
 
 
Where:
 is the final velocity of the projectile
 is the final velocity of the projectile
 is the initial velocity of the projectile
  is the initial velocity of the projectile
 is the time
 is the time
Solving:
 
 
 This is the acceleration of the projectile
 This is the acceleration of the projectile
