Can a number be accurate but not precise?
no only if it is precise it is accurate
Is it possible to get a precise measurement that is not accurate?
Certainly. Precision and accuracy do not mean quite the same thing. All measuring tools need to be recalibrated from time to time against a standard. For instance you can get a very precise reading from a micrometer or vernier gage but if it has not been correctly calibrated the reading will not be accurate.
How accurate are digital weight scales?
Digital weight scales have been proven to be very accurate. The way in which they work is by measuring the change in resistivity of the wires that are inside of them when a weight is placed upon them. This technique for measuring weight is very accurate and very precise. If you are looking for a scale with accuracy within .005 of an ounce, then digital is the way to go.
How precise is your measurement?
It depends on the measuring instrument that you use (including its calibration), how careful you are, how many measurements you take, whether or not you have allowed for external factors that could affect your measurement.
Why is 8.1956 most precise measuring device?
It is not; there are more precise measurements.
What instrument is most precise in measuring location on ocean?
The Global Positioning System (GPS) is the most precise instrument for measuring location on the ocean. It uses satellites to provide accurate location data in real-time.
Is less precise instrument always more accurate?
No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).
What do you call Marks and numbers on measuring instrument?
Marks and numbers on a measuring instrument are typically known as the scale. The scale is used to quantify measurements and provide a numerical value for the dimension being measured. It allows for accurate and precise readings to be taken from the instrument.
What instrument which would be more accurate for measuring the volume of a liquid?
A graduated cylinder would be more accurate for measuring the volume of a liquid compared to a beaker. This is because graduated cylinders have more precise volume markings and allow for more accurate readings due to their narrow and uniform shape.
Which is most accurate burette beaker measuring cylinder and volumetric flask?
The most accurate of these instruments is the volumetric flask, as it is typically calibrated to contain a specific volume at a specific temperature. Burettes can also be very precise when reading volumes of liquids being dispensed. Measuring cylinders are less precise than burettes and volumetric flasks. Beakers are the least accurate for measuring precise volumes due to their lack of a precise scale.
Why is it possible to be more precise when measuring in millimetres rather than centimeters?
A millimetre is smaller than a centimetre. When you have an instrument that can detect lower levels (lower LOQ), you can be more precise. This instrument, when measuring lower numbers, will convert cm to mm for instance.
How accurate is a bomb calorimeter?
A bomb calorimeter is a highly accurate instrument for measuring the heat of combustion of a sample. It can provide precise and reliable data on the energy content of different materials, making it a valuable tool in various fields such as chemistry and food science.
A balance would be the best tool for measuring?
A balance is a precise instrument used to measure mass of objects by comparing them with known masses. It provides accurate measurements by balancing the object against standard weights. This makes it a reliable tool for tasks that require precise measurements of mass.
What tool used for measuring precise volumes of liquids?
A graduated cylinder is a common tool used for measuring precise volumes of liquids in a laboratory setting. It has markings along its length that allow for accurate measurement of the liquid volume.
What is the meaning of the word calibrated?
If you calibrate something it means that you mark an instrument with a scale of readings. To calibrate something also means that you compare the scale with a known scale of another instrument. This insures something is accurate.
What are two situations where you need to be extremely accurate measuring mass?
Calibrating scales. Creating precise mixtures.
Instrument measuring the exact position of a ship or an aircraft?
Aircraft and ships use GPS locators for precise positioning.
