In separate experimental measurements by ten different students in a class for the value of the acceleration due to Earth's gravity in the same laboratory, the following results (in m/s2 ) were found: 9.82, 9.79, 9.68, 9.83, 9.81, 9.78, 9.72, 9.84, and 9.86. What is the precent error of the average value if the accepted value of g at that location is 9.81m/s2

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

Wavelength = pie*69+69 with ur mom

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
