+13x +10y -3x -4ysimplified is+10x +6y.I think this write but not really he use the method write
Use the LOG key, divide the result by 3 then use the 10x key.
The decibel is the common measure of sound intensity You can either use logarithmic calculators to add together two decibel values or you can ... ? 10 log (10x inverse log dBvalue/10 + 10x inverse log dBvalue/10) =
40
Use (-b + or - sqrt(b^2-4ac))/(2a) A is 10 B is -9 C is -6
You should have already used the Coarse adjustment on 10x so when you switch to 40x, all you need to do is fine adjust it. Plus, you don't want to break it by turning the Coarse up all the way.
On a the microscope I use, the ocular (eyepiece) has a magnification power of 10x. The 'low' (or 'scanning') objective lens is 4x, the 'medium' has a power of 10x, and the 'high' has a power of 40x. Multiply the ocular by the lens you're using to get your 'total magnification.' TIP: Only use the coarse adjustment knob while on 'low' power, then use the fine adjustment. Why? If you use the coarse adjustment knob on 'medium' or 'high,' there's a good chance you'll crack your slide. -BugCrunch
The answer is in the name. To focus the material or substance for a better/clearer view.
Either Fine or Coarse adjustment.
I assume you would use the fine adjustment knob for high power objectives.
The coarse adjustment knob is only used with the low-power objective lens (usually 4x) because all the other ones are too long and the coarse adjustment knob may bring the slide up too qucikly, therefore it might break the slide or crush the specimen being observed. When using the medium (10x) and high (40x) power objective lens, it is best to use the fine adjustment knob to focus on the details instead.
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
MP=(d/L)*(1-(L-l)f) where d would be the distance from the eye to the image without a lens L is the distance from the eye to the new virtual image (with a lens) l is the distance from the eye to the lens this equation only covers a single lens (whereas there tend to be two in a microscope), but that's no worry; use it twice! (i.e treat both lenses as independent sources of the image)
Rotate the revolving nosepiece to the appropriate objective (10x, 50x, etc.), then use the adjustment knob to sharpen the image and get rid of any blur.
The objectives are what magnify an item. They are usually 10x, 40x, and 100x. These are also known as low power, high-dry, and oil immersion. Some microscopes also have a 4x for quick scanning.
The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.
It is possible to use 10x instead of thanks in the internet community. The phrase 10x is considered internet slang. One could also use 10x in text messages they send to friends. When asked, one may want to explain what 10x means.
