Suppose that when two magnets are 0.06 meter apart, there is a force of 4 newtons. Find the work, in joules, that is required to move the magnets from a distance of 0.02 meter apart to a distance of 0.09 meter apart. (1 Joule = 1 Newton * 1 meter) Round your answer to three (or more) decimal places.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.
