what is the number supposed to be if you git 7 cm? Percent error is the percentage that you're incorrect by, so you need another measurement.
to do it, you find the difference and then divide by the original so (7-x)/true value then multiply by 100 to get percentage.

Percent error formula?
Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.
When an error of 1 percent is made in the length of a square the percentage of error in the area of a square will be?
area= side^2 let the symbol # denote error in measurement #area/area= 2(#length/length) #area/area*100= 2(#length/length)*100 percent error in area= 2*percent error in length=2% 2 per cent
What is a percent error?
It is a measure measurement of the amount of error made in an experiment. It is obtained by comparing the actual result, with the result gotten from the experiment. % error = [(experimental value - true value) / true value] x 100
Are percent deviation and percent error the same?
no
Can the answer of a percent error problem be 300?
Yes, your percent error can be over 100%. This means that somewhere during your experiment you made a big error.
What is the percent error of 7cm.?
7.14%
Percent error of 7cm?
The answer is likely to be 7.14% approx.
Which property of a measurement is best estimated from the percent error?
Measurement error: obviously!
Percent error formula?
Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.
If error in the measurement of momentum of a particle is 100 percent then the error in the measurement of kinetic energy is what?
If the error in the measurement of momentum is 100 percent, then the error in the measurement of kinetic energy will be 200 percent. Since kinetic energy is proportional to the square of momentum, if the momentum is off by 100 percent, the kinetic energy will be off by 200 percent.
How do accuracy and precision of measurement affect calculated values and percent error?
The more precise your instruments of measurement are, the less percentage of error you will have.
If percent error in measurement of mass is 3 percent and percent error in measurement of velocity is 4 percent then what will the percentage error in measurement of kinetic energy?
The percentage error in kinetic energy can be calculated by summing the percentage errors in mass and velocity. Therefore, the percentage error in the measurement of kinetic energy would be 7 percent (3 percent + 4 percent).
What is the percentage error of a length measurement of 0.229 cm if the correct value is 0.225 cm?
.229/.225 = 1.0178 percent error = (1.0178 - 1) times 100 to get to percent = .0178 x 100 = 1.78%
Find the greatest possible error and the percent error for each measurement 3cm 6cm 36.85g?
.5cm/.5cm/.005g
What are percent errors?
A percentage error for a measurement is 100*(True Value - Measured Value)/True Value.
What is the percent error of 4cm?
A percent error depends on the size of the measurement as well as the error itself. It's very intuitive to think about: If you're measuring a piece of paper and you're off by 4 cm, you'll have problems; if you're measuring the moon, that's nothing. A bigger percent error is a bigger deal to an engineer. You can calculate it the same way as any percentage: Divide the error by the total length of the measurement, then multiply by 100 to convert it from a proportion to a percentage.
When an error of 1 percent is made in the length of a square the percentage of error in the area of a square will be?
area= side^2 let the symbol # denote error in measurement #area/area= 2(#length/length) #area/area*100= 2(#length/length)*100 percent error in area= 2*percent error in length=2% 2 per cent
