To simulate the mechanical vibration of a structure, a 10 V battery is used to charge a 470 mF capacitor. The capacitor is then removed from the battery and connected to the terminals of an inductor. The circuit then oscillates and the maximum current through the inductor is 956 mA. What is the value (in Henrys) of the inductance ? To make life easy, assume the components are ideal. Give your answer in the form "a.bc times 10^(x) H".

(1 point) Mechanical engineers are studying the influence of cam shape on the vibration produced at a given set of frequencies. An experiment is run in which the vibrations produced by four common cam shapes are measured and compared. Three specially made test cams are used. Each cam is divided into four sectors and each sector is machined to a different one of the four shapes. Thus all four shapes appear on each test cam. The test cams are run...
