1. less solar energy
2. everything would be flipped, for example summer would be cold and winter would be warm.
 
        
                    
             
        
        
        
Answer:
32 mm
Explanation:
The field of view is the total area visible through the microscope
. The diameter of the field of view can be measured.
There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion. 
The relationship between field diameter and magnification is:
magnification of A * field diameter of A = magnification of B * field diameter of B
120X * 8 mm = 30X * B
B = 120X / 30X * 8 mm
B = 32 mm = 32000 μm
The field diameter of 30X magnification is 32 mm (32000 μm)
 
        
             
        
        
        
Some energy is always lost as heat 
hope that helps! :))
