Answer:
200x
Explanation:
<em>The total magnification of a microscope depends on the power of the eyepiece and that of the objective lens. It is obtained by multiplying the two factors together. </em>
The total magnification of a microscope can be mathematically expressed as:
Total Magnification = <em>ocular/eyepiece magnification x objective magnification</em>
In the illustration, eyepiece magnification = 10 and objective magnification = 20. Hence,
Total Magnification = 10 x 20 = 200x
Bond order is less in solid phases (usually 1), intermediate in liquid (2 or 3), and greatest in gases (3). [Be2]+ has a bond order of 1/2 and for [Be2]-, it has a bond order of 0. The bond order for <span>[Be2]+ is calculated by:
(4 bonding e- - 3 nonbonding e-) / 2 = 1/2</span>
1:) <span>Zn + 2 HCl = ZnCl2 + H<span>2
</span></span>2:) 4 Fe + 3 O2 = 2 Fe2O3
(a) The speed of light in the unknown substance is determined 1.82 x 10⁸ m/s.
(b) The light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.
<h3>What is the speed of light?</h3>
The speed of light passing from air into the substance is calculated as follows;
refractive index = speed of light in air / speed of light in the substance
speed of light in the substance = speed of light in air/refractive index
speed of light in the substance = (3 x 10⁸) / (1.65)
speed of light in the substance = 1.82 x 10⁸ m/s
Thus, the light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.
