Explain how a series of measurements can be precise without being accurate?
yes
What determins the precision of a calculated result based on measurements?
the precision of the least precise measuement
Which one of the measurements is precise 1009mm56ft132in81yd?
1009 mm1009 mm1009 mm1009 mm
Why is precise measurements important?
It is important because PRECISE means exact, and exact measurements are important because it tells you the actual measurement of an object, other than to tell you an estimate, not knowing the exact measurement of that object
Why are measurements always uncertain?
Because the results we get when we calculate measurements are estimated or rounded up as some people say, so being around the true answer is called accurate. Also, the devices we use to measure ( scales are an example of this) are never actually perfectly precise in how they are set, plus they are not completely clean which can change your answer. this change would not seem to be alot though it's not the true or exact answer.
Which of the methods of timekeeping is the most precise?
stopwatch
What lab equipment is used to measure time?
A stopwatch or timer is commonly used to measure time in a laboratory setting. Some experiments may also use more precise devices like digital timers or chronometers for accurate time measurements.
Why is 8.1956 most precise measuring device?
It is not; there are more precise measurements.
Which two measurements are the most prrecise?
Radio-Telescope measurements are the most precise
Can a measurements be both precise and accurate?
yes...
What determines the precision of a calculated result based on measurements?
The precision of a calculated result based on measurements is determined by the precision of the measurements themselves. The more precise the individual measurements are, the more precise the calculated result will be. Additionally, the number of significant figures in the measurements and the mathematical operations involved also affect the final precision of the result.
What is the meaning of this sentence they observed precise measurements in constructing pyramids?
It means they (the builders, or architects) possessed/had very precise(exact) measurements when they were constructing (building) the pyramids.
What is an advantage of a stopwatch?
A stopwatch provides accurate timing and allows for precise measurement of durations or intervals, which is useful for timing activities or events. It can help improve performance by tracking time and setting goals for improvement.
What is the most precise measurment 6cm or 2.5cm?
2.5cm is the most precise measurement of the two measurements.
How precise are measurements to instruments?
They depend on the design of the instrument.
What is the uncertainty in measurement when using a stopwatch to measure time?
The uncertainty in measurement when using a stopwatch typically depends on the stopwatch's resolution and the human reaction time involved in starting and stopping the watch. It is generally recommended to estimate the uncertainty to be half of the smallest division on the stopwatch. To reduce uncertainty, multiple measurements should be taken and averaged.
Is it true that an answer is as precise as the most precise measurement from which it was calculated?
Yes, the precision of an answer depends on the precision of the measurements used in the calculation. The number of significant figures in the answer should match the least number of significant figures in the measurements.
