مواسع ذو صفيحتين
متوازيتين مساحة كل من صفيحتيه (10) سم والبعد بينهما (17,7) مم، إذا شحن حتى أصبح جهده (100) فولت فإن الطاقة المختزنة فيه بوحدة النانو جول تساوي: (ع ) = (8.85*10^12) كولوم/ نیوتن.م
السعة C هي مقدار الشحنة المخزنة لكل فولت ، أو C = QV C = Q V. تبلغ سعة مكثف اللوحة المتوازية C = ϵ0Ad C = ϵ 0 A d ، عندما يتم فصل الألواح عن طريق الهواء أو الفضاء الحر.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
