Answer:
 = 1.9 cm
  = 1.9 cm
Explanation:
The magnification of a microscope is the product of the magnification of the eyepiece by the magnifier with the objective
     M = M₀ 
Where M₀ is the magnification of the objective and   is the magnification of the eyepiece.
 is the magnification of the eyepiece.
 
The eyepiece is focused to the near vision point (d = 25 cm)
         = 25 /
 = 25 /   
The objective is focused on the distances of the tube (L)
      M₀ = -L / f₀
Substituting
      M = - L/f₀    25/ 
  
1) Let's look for the focal length of the eyepiece (faith)
       = - L 25 / f₀ M
  = - L 25 / f₀ M
      M = 400X = -400
       = - 12 25 /0.40 (-400)
  = - 12 25 /0.40 (-400)
       = 1.875 cm
  = 1.875 cm
Let's approximate two significant figures
      = 1.9 cm
  = 1.9 cm
 
        
             
        
        
        
Answer:
A
Explanation:
The weight is acting downwards where as the buoyant force acting upwards (opposite) direction with equal amount of force. so the opposite forces cancel out each other (because of the force amount being equal) and no net force is acting on the object.
Hope i have helped you
Thanks.
 
        
             
        
        
        
Answer:
Explanation:
Newton's first law of motion:
An object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.
Newton's second law:
The net force on an object is equal to its mass times its acceleration.
Newton's third law:
For every action, there is an opposite and equal reaction.
 
        
             
        
        
        
Answer:
 daughters cells
Explanation:
when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. 
 
        
                    
             
        
        
        
Are there any options??
I would have to say metal of course but without options I can't assume anything
