السلام عليكم ..
هذه مسائل عجزت عن حلها ارجو المساعده حيث انه امتحاني لدخول الجامعة غدا في الساعه 8 صباحا وتذكروا الحديث بما معناه( من فرج عن مسلم كربة فرج الله عنه يوم القيامه)
A gas in a cylinder has a pressure of 5 x 105 Pa. What is the new pressure of the gas if
the volume is halved and the temperature (in Kelvin) is doubled?
A 2 kg mass is dropped from a building. What is its kinetic energy after 1 second?
[Take the acceleration due to gravity as g = 10 ms-2.]
A voltage of 8 V is applied to a 4 ohm resistor. What current flows through the
resistor?
E2. A 2μF capacitor and a 4μF capacitor are in series with a 6 V voltage source. What is
the charge on the 4μF capacitor?
