Answer:
dark-field microscopy
Explanation:
A darkfield microscope can be regarded as a brightfield microscope with a significant modification to condenser. There is an opaque disk, with a diameter of about 1cm placed in between the illuminator and condenser lens, the disk responsible for the blocking of most of the light from the illuminator, passing through the condenser to objective lens , which will then form hollow cone of light that has its focus on the specimen. Using a darkfield microscope the light that get to the objective is the only refracted or reflected light of structures in the specimen. And the image formed usually display a bright object with a dark background.
It should be noted that darkfield microscope is a type of microscopy works by allowing only light waves that have reflected from or refracted though the sample to enter the lens system.
Answer:
3, it's the igneous rock, sedimentary rock, and metamorphic rock i believe
Explanation:
Answer:
W= 638.1 J
Explanation:
As we know that
Work done is the area of the force and displacement diagram.
W=∫F.dx
W=Work
F=force
dx=Elemental displacement
From the diagram ,area A
A= 60 x 7.09 + 1/2 x 60 x 7.09
A= 638.1 J
So the work W
W= 638.1 J
The choice
which is the best name for these experiments would be Boyles' Law,
because it describes what will happen in the relationship between the pressure
and volume of the gas and Boyle’s Law is <span>is an experimental </span>gas law<span> <span>that describes how the </span></span>pressure<span> <span>of a </span></span>gas<span> <span>tends to increase as the </span></span>volume<span> of a gas decreases.</span> The correct answer between all the
choices given is the second choice or letter B. I am hoping that this answer
has satisfied your query about and it will be able to help you, and if you’d
