Hey! If this is on big ideas get a app called “Slader” It has answers to all math problems just like up the book you use > save it > type in the section you are doing > and look for the problems you are doing.
        
             
        
        
        
I believe it would be D a change in direction of motion
        
                    
             
        
        
        
To solve this problem we will use the concepts related to Magnification. Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
The overall magnification of microscope is

Where
N = Near point
l = distance between the object lens and eye lens 
 = Focal length
= Focal length 
 = Focal of eyepiece
= Focal of eyepiece
Given that the minimum distance at which the eye is able to focus is about 25cm we have that N = 25cm 
Replacing, 


Therefore the correct answer is C. 
 
        
             
        
        
        
False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.
