Question

A scale measures the weight of a light object to be 11.000 lbs ± 0.034 lbs. what is the uncertainty if this same scale is use to measure an object that weights 78.000 lbs? Assume that the percent uncertainty of the scale remains constant
1)0.034lbs
2)0.044lbs
3)0.310lbs
4)0.240Ibls

Answer 1

The uncertainty of the heavy object if the scale remains constant is 0.24 lbs.

What is uncertainty in measurement?

• This is the error associated in an attempt measure the object accurately.

The percent uncertainty in measuring the light weight object is calculated as follows;

$= \frac{0.034}{11} \times 100\%\\\\= 0.309\%$

The uncertainty of the heavy object if the scale remains constant is calculated as follows;

$= \frac{0.309}{100} \times 78.0 \ lbs\\\\= 0.24 \ lbs$
