Why is it helpful for a microscope to be parfocal?
Once the object is in focus with lowest power, it should also be almost in focus with the higher power.
Why is slide centered before moving to higher power on microscope?
When you switch to high power, you are focusing on a very small part of the large picture. If you center your object under low power (preferably by the little black arrow most microscopes have) you will see the object you are looking at 100% of the time. If you do not center your object, the object will end up being off to the side of what you are looking at in your field of view. It's kind of like zooming in on a map on the internet, you have to center what you want to zoom in on or else you will zoom in on an area you did not want to look at.
How should the course adjustment on a microscope be turned under low power?
I'm not sure if I understand the question. When using a compound microscope, you always want to start by adjusting the coarse adjustment under low power (like 4x) until you have whatever you are looking at in focus. Then, without moving the adjustment, go to the next power (like 10x or something) and use the coarse adjustment only a little and then use the fine adjustment to get it into focus again. Without touching anything, switch to the next power (say 40x) and DO NOT TOUCH THE COARSE ADJUSTMENT. You will lose your object and have to start all over. Only use the fine adjustment past this point. Again, focus as best as you can. This will depend on the microscope, but some also have a 100x power objective lens. It is best to put a drop of immersion oil onto your sample while you move from 40x to 100x. Then you should only use the fine adjustment a small amount to get your sample into focus. The immersion oil improves the resolution of the image that hits your eye, making it easier to see and not blurry.
What is also known as the 'focus' - the place underground where an earthquake originates?
The Underground center of an earthquake is called the focus.
If all forces are equal and opposite how does anything accelerate?
Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects! The forces on object A, and on object B, may be unbalanced!Because NOT all forces are equal and opposite.

What the camera autofocusing?
Auto Focus on a camera is the camera is focusing on the main object in the photo and blurring out the rest of the background around the object or person, you can turn it off, and its AUTO because it focuses on the object which it thinks is the main object. You can also focus manually.

What is parfocal capability?
lenses: set up or arranged so that when one lens is changed for another, there is no change in focus. * Applied usually to turret mounted lenses e.g. on microscope; also in telescopes: ~ eyepieces: changing one for another does not require refocusing. * When the distance from the object to the rear principal plane of each lens is equal, they are said to be parfocal.
What object does an unbalanced force have on an object?
An unbalanced force can completely destroy the object (depending upon its mass and power of force) or can gradually move it or it can also have no effect on the object.
What is the blinker on a computer screen?
A blinking object to indicate where to type is called a cursor. The mouse pointer is also called a cursor.

What is the definition of far sightedness?
== Hyperopia, also known as farsightedness, longsightedness or hypermetropia, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.
Definition specific powers?
Specific power can be defined as the percentage of power produced by a certain object to its mass. Specific power can also be acquired by humans from the authority entrusted to them.
