Answer:
The answer is "c,d,e, and g".
Explanation:
The correct choices can be defined as follows:
- Higher-frequency microwaves aren't used in any of these systems.
- Infrared waves aren't seen in each of these technologies.
- Its shortest wavelength of all of the technologies listed is the above radiation generated by certain wireless networks.
- These devices all produce waves of wavelengths ranging from 0.10 to 10.0 cm.
 
        
             
        
        
        
Answer:
11.1 m/s
Explanation:
120 km = 120 x 1,000 = 120,000 m 
3 hours = 3 x 60 x 60 = 3600 x 3 = 10,800 s
speed = 120,000 / 10,800
= 1200/108
= 11.1 m/s
 
        
                    
             
        
        
        
Answer:
evolutionary theory
Explanation:
The evidence is overwhelming that the Grand Canyon was dug over a span of millions of years by the erosive power of the Colorado River and that river’s tributary streams. 
This evidence does not support catastrophic theory but it does support evolutionary theory, because it was gradual process and took place overtime. It did not happen in a catastrophic manner.
