True
No single instrument can measure both of those quantities.
An accurate measurement is made with a pH-meter; pH-papers make only approximative determination.
I'm convinced that it was the clarinet. No, I'm just joking. The truth is that I have no lab, I used no instruments, I made no measurements, and someone has taken the cylinder.
So They Can Have The Accurate Answers
The concept that the world is susceptible to measurement is the basic premise of the cartographic process. The rest of the process assumes that we can make reliable models of these measurements.
Interferometry is a measuring instrument that uses an interference pattern to make accurate measurement of waves. This instrument uses optical, acoustic, and radio frequencies.
We need standard unit for measurement to make our judgement more reliable and accurate. For proper dealing, measurement should be same for everybody. Hope this helped :>
Make sure you are only measuring what you are after. Not noise and local disterbances. Proper system grounding is needed. Make sure the device you are using has been calibrated periodically properly to a N.B.S. standard. Your measurement will only be accurate to 10 times the standards value. That is a 0.3% accurate standard will only give you a 3% accuracy in your measurement.

The details depend a lot on what you want to measure.
Repeated trials of the same measurement are desirable to increase the reliability and accuracy of the results. By taking multiple measurements, any variations or errors can be identified and mitigated, leading to more robust and trustworthy data. Additionally, repeating the measurement helps to reduce the impact of random fluctuations and outliers, providing a clearer picture of the true value being measured.
Never: A measurement made is always an approximation. We can get very close to being accurate with our measurements, but never fully 100% accurate. This is not the fault of the person measuring, or what tool they are using to measure with, but it is a natural law that we (anyone, even superior aliens to humans) cannot ever fully make an absolutely accurate measurement.
i DO NOT NO.
They want to check that it is accurate.
No single instrument can measure both of those quantities.
Going into a smaller scale, such as to make Cm (Centimeters) more accurate, you go into Mm (Millimeters). There are smaller scales of everything, it is just about how accurate you want to make it.
It all depends on which website. Most of them are reliable. Make sure they are official, if they are then they should be reliable and should give you accurate information.
