1. a) In order to sharpen the objective with a 40x objective (400x total magnification), the objective must be closer to the sample than with a 10x objective (100x total magnification), so the sample is out of focus.
b) At 400x total magnification, the field of view is narrower than at 100x total magnification.
c) A 40x objective (i.e. 400x total magnification) has a higher numerical aperture than a 10x objective (i.e. 100x total magnification) and therefore provides better resolution.
d) Shallow depth of field.
e) The amount of light is reduced.
f) Shorter working distance.
2. The best objective for observing bacteria is the 100x objective, which is the immersion objective.
3. Without the addition of immersion oil, the sample will look blurry and will not give maximum resolution.

Answer:
The rate at which the pump moves oil is 1 m³/s
Explanation:
Assumptions:
- there is steady-state flow
- oil and water are incompressible
- first fluid is water, second fluid is oil and third fluid is the mixture of oil and water.
where;
ρ is the fluid density
Q is the volumetric flow rate
Substitute in Q₃ in equation i
divide through by ρ₁
Make Q₂ the subject of the formula
Therefore, the rate at which the pump moves oil is 1 m³/s
Answer:
The force is of the weight <u>862,4 Newtons.</u>
<u></u>
Explanation:
We have the formula:
w = m * g
Data:
w = weight = ¿?
m = mass = 88 kg
g = gravity = 9,8 m/s
Replacing according formula:
w = 88 kg * 9,8 m/s
Resolving:
w = 862,4 N
