( ) You ( ) A six inch cooper wire ( ) A 12 inch copper wire ( ) A 1 meter iron rod Which kind of earthquake wave is purely longitudinal? ( ) the p-wave ( ) the l-wave ( ) the s-wave ( ) the the r-wave Which kind of light has the longest wavelength? ( ) red light ( ) blue light ( ) infrared light ( ) ultra violet light When an object is short of electrons, it ( ) has a negative charge ( ) has a positive charge ( ) has a low resistance ( ) glows (e.g. lightbulb wire) Radio waves and x-rays have the: ( ) same frequency ( ) same speed ( ) same wave length ( ) same surface area ( ) none of the above A shaped charge in an explosion does more damage because: ( ) The sharp shape cuts the object ( ) The shape focuses the power ( ) It adheres to the object ( ) It disguises the explosive If an earthquake wave reaches an area that has slow wave speed, the amplitude is: ( ) increased ( ) decreased ( ) stays the same What is a coulomb? ( ) 6X10^18 electron charges ( ) the energy of one electron at a potential of one volt ( ) one cubic kilometer per second ( ) one ohm per second ( ) the charge on one electron Which of the following statements about earthquakes is true? ( ) S waves are fastest and cause the most destruction. ( ) P waves are fastest and L waves cause the most destruction. ( ) L waves are slowest and P waves cause the most destruction. ( ) P waves are fastest and cause the most destruction. The Tesla coil was useful because: ( ) it allowed there to be a powerplant in every neighborhood. ( ) it made the high voltage less dangerous ( ) it decreased the current going through long wires to reduce the loss of electricity. ( ) it was given strong support by Thomas Edison, who popularized it
