In an experiment, the speed of sound waves on Earth at sea level at a temperature of is 333 m/s. Find the percent relative error in the measurement using an accepted value of 344 m/s. Give your answer to one decimal place.
Which of the following is the correct formula for the value of the relative error of the measurement given the accepted value, , and the absolute error, ?
An experimental apparatus for measuring the acceleration due to gravity produces an absolute error of 0.05 m/s2. The apparatus is used on two different planets. One planet has an accepted value for its gravitational acceleration of 3.72 m/s2 and the other has an accepted value for its gravitational acceleration of 8.87 m/s2. Find the difference between the percent relative errors of the measurements of gravitational acceleration made by the apparatus on the two planets. Give your answer to one decimal place.
