Over a period of operation, the useful work output of the fluorescent bulb was 4.24 x 105 J, produced from a total work input of 2.11 x 106 J. What is the efficiency
of this bulb?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

In a series circuit the __ is the same at every point

The ability to make things happen is also called a. heat b. force c. matter d. energy
