Images look larger through convex lenses. Since Saul is wearing convex lenses, he must be farsighted.
Answer:
From the figure,
The free-body diagrams for and are shown in the figures below. The only forces on the blocks are the upward tension and the downward gravitational forces and . Applying Newton’s second law, we obtain:
which can be solved to yield
Substituting the result back, we have
(a) With and , the acceleration becomes
(b) Similarly, the tension in the cord is
Volume = mass / density = 45.6/10.5 = .... L
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.

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.

<h2>Answer :</h2><h2 />
Work is the amount of energy transferred. As per the formula
Work = Force x Distance [moved toward the direction of the force]
So as per the formula
<u>Solution : </u>
Force = 825 N
Distance = 35 m
Work = 825 (n) x 35 (m)
Work = 28875 Joules
