The length of a wire 2.00 m is measured as 2.02m. What is the percentage error in the measurement?

Respuesta :

Answer:

1%

Explanation:

Percent error can be found by dividing the absolute error (difference between measure and actual value) by the actual value, then multiplying by 100.

[tex]Percent Error=\frac{V_{measured}- V_{true} } {V_{true}} *100[/tex]

The measured value is 2.02 meters and the actual value is 2.00 meters.

[tex]V_{measured}=2.02\\\\V_{true}=2.00[/tex]

[tex]Percent Error=\frac{2.02-2.00}{2.00} *100[/tex]

First, evaluate the fraction. Subtract 2.00 from 2.02

[tex]Percent Error=\frac{0.02}{2.00}*100[/tex]

Next, divide 0.02 by 2.00

[tex]PercentError=0.01 *100[/tex]

Finally, multiply 0.01 and 100.

[tex]Percent Error=1\\Percent Error= 1 \%[/tex]

The percent error is 1%.
