Distance between the centers of the two objects are the second object
        
             
        
        
        
To solve this problem we will apply the concepts related to the balance of forces. Said balance will be given between buoyancy force and weight, both described as derived from Newton's second law, are given as
Buoyancy force

Here,
V = Volume
 =Density of air
=Density of air
g = Acceleration due to gravity
Weight

m = mass
g = Gravity 
Our values are given as,




Then,

Replacing,

Now net force is ,

Mass of the sphere is 

Now acceleration of the sphere is 



Therefore the acceleration of the sphere as it falls through water is 
 
        
             
        
        
        
Hello! There are many indicators to show a sign that a chemical reaction has occured. These are 3 as followed.
1. An odor is produced.
2. A change in temperature.
3. A color change.
Others can be a formation of a solid or a gas.

Explanation:
after 5 seconds, the velocity is (5s)(3m/s²) = 15m/s
The displacement after 5s is 
x=vo + (1/2)at²
x = 0 + (1/2)(3m/s²)(5s)(5s)
x= 37.5 m
