In this problem you must determine the intensity of a sound wave when it reaches a given location away from its source.

Determine the resistance of a wire based on its composition and its physical dimensions. Then give the area of the wire in square meters and the resistance of the wire in Ohms.

Determine the resistance of a wire based on its composition and its physical dimensions. Find the current that would flow through the wire when the wire is connected to a certain voltage.

In this problem you will have water flowing through an underground pipe and then passing into a ground level nozzle to create a fountain. Based on the pressure in the pipe you will find the speed of the water in both sections of the pipe...

In this problem, water is flowing through two sections of piping with different diameter pipes joined by a coupler. Given the speed of the water in the first section of piping, find the speed in the second section.
