A10.0 μf capacitor is charged so that the potential difference between its plates is 10.0 v. a 5.0 μf capacitor is similarly charged so that the potential difference between its plates is 5.0 v. the two charged capacitors are then connected to each other in parallel with positive plate connected to positive plate and negative plate connected to negative plate. how much energy is "lost" when the two capacitors are connected together? 33 × 10-6 j42 × 10-6 j63 × 10-6 j130 × 10-6 j560 × 10-6 j

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
