How do you calculate the density of a non-uniform object?
The density of a non-uniform object can be found by using its mass and volume. The volume can be measured by placing the object in volumetric glassware filled with water. The increase in volume is equal to the volume of the object. The object can then be weighed using a scale. The density of the object will be given by the ratio of mass / volume.
What is proper ways of handling and manipulation microscope?
Manipulate a MicroscopeInstructions1Set up the microscope on a flat surface. Always carry the microscope using two hands if the microscope must be transported from one area to another. One hand should support the bottom while the other hand is holding the arm. Once in place, remove the any covers and plug in the microscope.2Position the slide onto the stage. Clip it into or under the slide holders. Turn on the light from the illuminator under the stage. Center the slide the best way possible without using any focusing knobs or the eyepiece.3Look through the eyepiece, keeping both eyes open to avoid eye strain, while using the course focus knob to bring the stage and slide closer to the objective, which is the lens that extends below the eyepiece, until the object can be seen through the eyepiece. Use the fine focus knob (which will also be on the side of the microscope) to bring the image into sharper focus.4Center the object being viewed. Change the iris diaphragm under the stage using the level to open and close the iris. Change the amount of light entering the specimen as needed. Changing the amount of light going through the slide may show additional details not seen at higher light levels.5Change to the 10X objective which is the next longest lens by rotating the lens pieces. The object should appear larger and only require using the fine focus knob to bring it into sharper detail. Use the iris diaphragm to change the amount of light entering the slide. Continue to the 40X objective and repeat. Each time the object will appear larger and you will be able to see less of the object at any one time while viewing.6Lower the stage and add one or two drops of immersion oil to the slide. Change the microscope to the 100X objective. Slowly raise the stage using the course focus until the objective is touching the oil. Use the fine focus knob to bring the object into sharp focus. Clean the slide and objective with lens tissue after use.7Return the stage to the lowest level. Change the objective back to the 4X lens. Unplug the machine and replace any covers. Carefully return the microscope using both hands to where it is stored.
What is an advantage of using low power on a microscope?
it allows you to focus your lens on the pbject.
What object using a directrix and a focus?

10
Which measure in the metric system is defined by using an object for a referent?
The kilogram is the measure in the metric system that is defined using an object for a referent. It was previously defined by a physical object known as the International Prototype of the Kilogram, but is now defined in terms of a fundamental constant of nature called Planck's constant.
When using a film camera what must you do to bring an object focus?
cows
What should be in place when the first attempt is made to focus on an object on a slide?
Before attempting to focus on an object on a slide, ensure the slide is centered, the objective lens with the lowest magnification is in place, and the stage is at its lowest position. Start by using coarse focus adjustment to bring the object into view, and then switch to fine focus to sharpen the image.
What to do first when using a microscope?
What you do first when you use a microscope you put the slide in. Then you focus the microscope. Then you look at the object you are supposed to or look at the object you want to.
How can you describe an objects position?
An object's position can be described in terms of its distance and direction from a reference point. It can also be described using coordinates in a given coordinate system. Additionally, relative positions can be described using terms like above, below, in front of, or behind another object.
What can the measurement of hotness or coldness of an object be defined by?
The measurement of hotness or coldness of an object can be defined by its temperature, which is a measure of the average kinetic energy of the particles within the object. The higher the temperature, the hotter the object, and the lower the temperature, the colder the object. Temperature is typically measured using a scale such as Celsius or Fahrenheit.
What do you do to get sharper images for photos?
Lack of desired sharpness in photos may be caused by the object being out of focus or movement of either the object or the camera. Using manual focus, a good lens and a tripod are a few ways to get sharper images.
What is the basic requirement for you to see an object using the microscope?
The object must be small enough to fit on the slide and within the focus range of the microscope.
What is an objects location?
An object has to be somewhere, so if it not here it must be there. The place where it is could be defined using a spatial reference frame.
What is coarse used for?
Coarse focus on a microscope is used only when you are using the lowest objective lens. You use it to get the object magnified mostly. The fine focus is then used to adjust the resolution to the viewer's eyesight.
