Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
- Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
- Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress. 
- An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem. 
 
        
                    
             
        
        
        
Answer:
see if the strips repel each other when brought close together
Explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance. 
Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.
