Question

The true value for a measurement is 24.36 m. The experimental value is 20.50 m. Calculate the percent error. Show all work with units and correct sig figs.

A) 15.80%
B) 18.18%
C) 17.65%
D) 16.88%

Answer 1

The percent error can be calculated using the formula |(Experimental Value - True Value) / True Value| × 100%. In this case, the percent error is 15.80%.

Step-by-step explanation:

To calculate the percent error, we need to compare the experimental value with the true value. The percent error formula is:

Percent Error = |(Experimental Value - True Value) / True Value| × 100%

Plugging in the given values: Percent Error = |(20.50 m - 24.36 m) / 24.36 m| × 100% = 15.80%

Therefore, the correct answer is A) 15.80%.
