Is measurements can be exact?
They cannot be because of errors that can be made by the measurer, calibration of instruments.
Would taking measurements of the same object several times and then averaging them give a more accurate measurement?
Generally, yes, because the averaging removes the effects of random errors in the measurements. However if your measurement technique has biases, these will not be removed through averaging and the averaged result will be biased.
Why do you need standard measurements?
We need standard measurements because it helps us to find the measurements of things.

Fannie Farmer
What are two types of errors in physics?
Two types of errors in physics are systematic errors, which result in measurements consistently being either higher or lower than the true value, and random errors, which occur randomly and can affect the precision of measurements. Systematic errors are usually due to equipment limitations or procedural mistakes, while random errors are caused by unpredictable variations in measurements.
What is different types of determinate errors?
Systematic errors: These are consistent errors that affect measurements in the same way each time, such as an incorrectly calibrated instrument. Random errors: These errors are unpredictable and can vary in magnitude and direction with each measurement, often caused by factors like human error or external conditions. Instrumental errors: Stemming from limitations in the measuring device, these errors can impact accuracy and precision of measurements.
What is a sentence for the word Introduced?
The producers introduced the star of the movie at its premiere. Using the wrong units of measure has often introduced errors into scientific calculations.
Is measurements can be exact?

What is the height from your shoulder to your fingertips?
The length from your shoulder to your finger tips varies from person to person. This was why a standard of measurements was introduced by law.
What has the author David Karo written?
David Karo has written: 'Electrical measurements and the calculation of the errors involved'
What system of measurements to most countries use?
Most countries follow "International System of Units " for measurements.This system was officially introduced in 1960 .
What process is designed to ensure the accuracy of measurements through routine performance of a set of operations designed to detect and than correct errors in the measurement instrument?
The process designed to ensure accuracy of measurements through routine operations is called calibration. Calibration involves comparing measurements from a device to a known standard and making adjustments if needed to correct any errors in the measurement instrument.
How can results of an experiment have a good accuracy by very poor precision?
An experiment can have good accuracy but poor precision if the average of the results is close to the true value but the individual measurements are widely spread out. This could be due to systematic errors that affect all measurements in a similar way, leading to good accuracy, but random errors that cause variation between individual measurements, resulting in poor precision.
What is error analysis of linear motion experiment?
Error analysis in a linear motion experiment involves identifying, quantifying, and evaluating sources of error that may affect the accuracy of the measurements taken during the experiment. This could include errors due to limitations of the measuring instruments, systematic errors in the experimental setup, or human errors in taking measurements. By conducting error analysis, researchers can estimate the uncertainties associated with their measurements and adjust their results accordingly to ensure the reliability of their conclusions.
