Increased lamp voltage is achieved by turning the light intensity dial.
To enlarge the diameter of the hole and let more light through the slide, the iris diaphragm was modified.
Condenser: Position it higher and closer to the slide's bottom to better direct light to the centre of the slide.
<h3>
How do you adjust the light level on a microscope?</h3>
Utilize the brightness adjustment knob to change the brightness. Turn the brightness control knob while looking through the eyepieces to make sure there is no glare in the field of view.
Use a daylight balancing filter if your compound microscope has a certain sort of illumination. It typically rests directly on top of the luminator or in a filter holder above the light. This filter is blue.
The daylight balancing filter will correct the colour temperature and produce a higher-quality image if your microscope is lighted by tungsten or halogen (and a better colour image). This blue filter is not necessary if your microscope is an LED.

Answer: D
Explanation: Energy is neither created nor destroyed so the amount of reactants and products must be equal
Answer:
Honda won by 0.14 s
Explanation:
We are given that
Distance =S=200 m
Initial velocity of Honda=u=0m/s
Initial velocity of Porsche=u'=0m/s
Acceleration of Honda=
Acceleration of Porsche's=
Time taken by Honda to start=1 s

Substitute the values




Time taken by Honda=11.55 s
Now, time taken by Porsche



Total time taken by Porsche=10.69+1=11.69 s
Because it start 1 s late
Time taken by Honda is less than Porsche .Therefore, Honda won and
Time =11.69-11.55=0.14 s
Honda won by 0.14 s
Answer:
VL=2107.6v
Explanation:
at resonance xc=xL
1/wc = wL
z=R
because sqr(R^2+(xL-xc))
^
(xL=xc)
V/R=I
90/28.9=3.1142A
w=1/sqr(1.31×(2.86×10^-6))=516.63
xL= wL
xL= 516.63×1.31=676.785
VL=3.1142×676.785
VL=2107.6v
