The gap between electrodes in a spark plug is d, 0.05 cm (not meters). To produce an electric spark in a gasoline-air mixture, there must be an electric field, E, of 3.5 x 10^6 V/m. What minimal potential difference, V, must be supplied by the ignition to start a car

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.

Which one of the following research methods can show cause and effect

More solar radiation is absorbed by earth’s surface than by
