Which measurement device is the most precise?

Which measurement device is the most precise?

An atomic clock is the most precise time measuring device because atomic oscillations are repeated with a precision of 1s in 1013s.

What is the most precise measurement ever made?

Carrying the fame of being one of the most precisely verified propositions in physics, the ratio of the gravitational to inertial mass was verified to be unity within 1 in 1015 by the MICROSCOPE satellite in 2017.

Which measuring device gave the most precise area?

caliper
The caliper is a more precise measuring tool because it can measure extremely small differences in length. The more precise the measuring tool, the more precise and accurate the measurements can be.

Which is the most precise instrument for measuring time?

The means, the device that can measure the smallest change in any unit is the most precise one. Hence, option b is the correct answer. Additional information: Atomic clock is the most precise time standard known, and it is used as primary standards for the distribution of time internationally.

What is the most precise tool in the world?

precision micrometer
The precision micrometer is the most accurate handheld tool available to skilled operators. Some examples of micrometers include digital, vernier, inside and bench.

Why is the pipette the most precise?

The long, narrow, and slender neck of the volumetric pipette makes it easier to measure and read the meniscus very precisely.

Which value is most precise?

All given measurements are correct up to two decimal places. As here 5.00 mm has the smallest unit and the error in 5.00 mm is least (commonly takes as 0.01 mm if not specified), hence, 5.00 mm is most precise.

What is the most precise measurement of the volume of this liquid?

graduated cylinder
A graduated cylinder is the most precise for measuring the volume of a liquid.

Which of the following is most precise measurement of the diameter of a wire?

Answer: The measurement 4.00 mm is most precise because it is measured with an instrument of minimum least count.

What are the two most common time measuring devices?

Explanation: clocks, simple pendulum, watches.

Which is the most precise device a or C?

Device A is most precise, while device C is the least precise after repeated measurements.

Which is an example of the precision of a measurement?

Consider the example of the paper measurements. The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the range, or difference, between the lowest and the highest measured values.

How are significant figures and precision of measured values related?

Precision of measured values refers to how close the agreement is between repeated measurements. The precision of a measuring tool is related to the size of its measurement increments. The smaller the measurement increment, the more precise the tool. Significant figures express the precision of a measuring tool.

Why is the caliper a more precise measuring tool?

The caliper is a more precise measuring tool because it can measure extremely small differences in length. The more precise the measuring tool, the more precise and accurate the measurements can be. When we express measured values, we can only list as many digits as we initially measured with our measuring tool.
