Why is it necessary to calibrate the 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 Precautions must be taken when talking measurements using a micrometer screw gauge?
Ensure the micrometer screw gauge is clean and free of debris. Use a steady hand to prevent any unnecessary movements while measuring. Make sure the object being measured is placed firmly between the anvil and spindle to avoid inaccuracies in readings.
What is the scale on the micrometer is used to measure too 0.0001?
The answer depends on the units used for 0.0001 : A micrometre is too crude to measure 0.0001 kilometres and not precise enough to measure 0.0001 nanometres. If you must ask questions about measurement units, perhaps you could try to ensure that you mention the relevant units with any measurements in the question!
Why must temperature always be in units of kelvin before using Charles law?
Temperature must be in Kelvin when using Charles's Law because it is an absolute temperature scale that starts at zero Kelvin, where molecular motion theoretically stops. Since Charles's Law involves the ratio of volumes and temperatures, using the Kelvin scale ensures consistency and accurate results in the calculations.
What device must always be zeroed out before egin to use it before measurement?
A scale or balance should always be zeroed out before using it to ensure accurate measurements. This process removes any potential errors or biases that may affect the measurement results.
What is the expected Error using micrometer?
the spindle must be tighten to avoid slightly changes on the reading
