An empty capacitor is fully charged in an RC circuit. What happens to the time to fully discharge the capacitor if the resistor in
the RC circuit is replaced by a resistor with smaller resistance?
The discharging time is longer than the charging time.
The discharging time is shorter than the charging time.
O The discharging time is the same as the charging time.
o It cannot be determined.

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

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.

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
