Is peat the early stage in the formation of coal?
Yes it is;because the 1st stage is Peat, 2nd stage Lignite, 3rd stage Bituminous coal, and 4th stage is Antheracite.
What is the first stage of a diamond?
The first stage of a diamond is carbon.
First stage of coal formation?
Fist Stage Of Coal Formation Is Called
What is the 2 stage of coal formation?
Lignite is the type of coal that is stage 2.
What salt bridge do in chemistry?
Functions of salt bridge are:It completes the circuit.It maintains electroneutrality of the solutions.Reactions can be stopped at any stage by removing the salt bridge.
What are the Function of magnifying parts?
Body - The frame of the microscope. Body tube - Inside "tunnel" of the microscope. Eyepiece - Where you look.Objective - That is the lens closest to the specimen. Focus fine tuning knob - Allows you to focus the image at a smaller, finer rate. Focus knob - Allows you to focus the image. Ocular lens - That is the lens in the eyepiece. Slides - Used for holding specimens. Specimen - What you are viewing. Stage - That is where the slide goes. Stage clip - That is a clip or spring for holding the specimen slides. Turret - Part that allows you to change objectives.
What is the difference between stage micrometer and ocular micrometer?
Ocular micrometers are see-through disks with a ruler in them that go in the eypiece of a microscope to measure what you are seeing. Stage micrometers are put on the stage/view platform of the microscope, so instead of putting them in the eyepiece you are putting them right next to the object you are looking at in the microscope.
What contains the various strength magnifying lenses of a light microscope?
The objective lenses are typically mounted in a rotating mount called a "nosepiece" which is located at the bottom of the ocular tube, just above the "stage" that holds the viewed slides.
How does the mircoscope work?
The microscope works because of two lenses (ocular and objective). The objective lens magnifies the object and produces a real image. This image is projected to the ocular lens and produces the virtual image, which is the one that the eye views. More specifically, light from substage bounces off a mirror and illuminates the object on the slide being viewed on the stage. The light is then bent into a parallel path and travels through the microscope tube (through the objective lens). Then the light is bent again into a small focus for the eye to view the magnified object through the ocular lenses. Switching the amount the object is magnified by switching the objective lens changes how much the light is bent.
What are the functions of the base and the arm of the microscope?
The base supports the stage and the arm; the arm supports the viewing ocular.
What are the functions of the base and the arm are of the microscope?
The base supports the stage and the arm; the arm supports the viewing ocular.
How do the graduations differ between ocular and stage micrometers?
By knowing the measurement of, and you use it to calibrate the ocluar lens of a microscope
Why is it necessary to calibrate to ocular micrometer with each objective?
The ocular micrometer is inside the ocular lens, it will not change size when the objectives are changed. Therefore, each objective lens must be calibrated separately. Ocular micrometers have no units on them - they are like a ruler with marks but no numbers. In order to use one to measure something under a microscope, you must assign numbers to the marks. This is done by looking through your OCULAR micrometer at a STAGE micrometer mounted on a slide. The stage micrometer is just a ruler with fixed known distances, so you can use it to tell how far apart marks are on the ocular micrometer. This has to be done because the marks on the ocular micrometer are different distances apart depending on the magnification used on the microscope. It must be calibrated for each objective.

What stage is Melting the toner image on the paper is referred to?
fusing image
If thirteen ocular divisions line up with two division of the stage micrometer what is the diameter of a cell that spans sixteen ocular divisions?
Two divisions of the stage micrometer is equal to 20 micrometers. 20 micrometers/13 = 1.54micrometers You multiply this by 16 to find the diameter of the cell. 1.54 x 16 = 24.62 micrometers
What is stage micrometer?
a tiny ruler that you know the measurements of, and you use it to calibrate the ocular lens of a microscope
