Why will the Alaskan Way Viaduct collapse? The Alaskan Way Viaduct will collapse because of an earthquake.The earthquake’s cause has to do with the layers of the Earth‚ mainly the lithosphere and the asthenosphere. The result of the lab “Density Column” proved that since the layers of the Earth are stacked on top of each other‚ like the liquids in the “Density Column”‚ the layers must have different densities. Another lab that was done in class‚ “Density Cubes”‚ showed that density‚ or

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of
