RUBBEDBALLOON VOLTAGE CALCULATION. I rub a balloon upon my arm hair. If I know the attraction force and the capacitance between those flat, platelike regions of opposite charge, then I can calculate the voltage.
Softball is a variant of baseball played with a larger ball (11 in. to 12 in. sized ball) on a smaller field. It was invented in 1887 in Chicago, Illinois, United States as an indoor game. The game moves at a faster pace than traditional baseball. There is less time for the base runner to get to first while the opponent fields the ball; yet, the fielder has less time to field the ball .
