اصلا مفيش حاجة اسمها دكتر بيفهم ودكتر ما بيفهمش

دكتورة مهجة في رأيى من أحسن الدكاترة، كفاية انها بتمشي بسرعة في المنهج لان الدكاترة اللى بيعيدوا المعلمة 6000000 بيخلونى اسرح







بالنسبة للpower

انا دورت ولقيت ده

he units of power are units of energy divided by time. The SI unit of power is the watt (W), which is equal to one joule per second. Non-SI units of power include ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV)), and foot-pounds per minute. One unit of horsepower is *****alent to 33,000 foot-pounds per minute, or the power required to lift 550 pounds one foot in one second, and is *****alent to about 746 watts. Other units include dBm, a logarithmic measure with 1 milliwatt as reference; (food) calories per hour (often referred to as kilocalories per hour); Btu per hour (Btu/h); and tons of refrigeration (12,000 Btu/h).
