There are a variety of weather tools, like barometers, anemometers, wind vanes, thermometers, and psychrometers. Pick two of these and research them online or using the references of your choice. Then write a description of each. Use these questions to help guide your description: When was the tool invented? Who invented it? How does it work? How is it used in predicting weather?

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.
