Question

Individual measurements introduce errors that may be large or small depending on the quality of the tools and processes used. Scientists use these equations to calculate error.
error = experimental value -accepted value

percent error = error / accepted value x 100

what is the maximum error allowed if the percent error must be no more than 10 %?

A. error x 0.1
B. accepted value x 0.1
C. experimental value x 0.1
D. (experimental value - accepted value) / accepted value x 0.1

Answer 1

Answer:

B. accepted value x 0.1

Explanation:

in the equation provided

$Percentage Error=\frac{Error}{AcceptedValue} X100$

Maximum allowed value of percentage error = 10%

put this value in the equation in stead of percentage error we get,

$10 = \frac{error}{AcceptedValue} X100\\ \frac{10}{100} =\frac{error}{AcceptedValue}\\.1=\frac{error}{AcceptedValue}\\error = .1 X Accepted Value$

so maximum error = .1 x accepted value

10 % percentage error means the experimental value has 10 % error compared to accepted value.so error will be 10 % of the accepted value

or .1 times of accepted value
