Suppose that when you inverted the eudiometer, a bubble of air became trapped inside it and the difference in volume was not accounted for in the calculations. Would this make your experimental value of R larger, smaller, or have no effect

During the 1800s. hope this !

Gotta have a picture ^^

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.
