(i) Calculate the current in the resistor 9.00 s after the resistor is connected across the terminals of the capacitor.
(ii) What charge remains on the capacitor after 8.00s? Hence calculate the maximum current in the resistor.
(i) Find the time interval required for the capacitor to reach this charge.
(ii) If R = 250 Kiloohm, what is the value of C?
(i) Calculate the energy stored in the capacitor
(ii) The battery is then disconnected from the capacitor; the capacitor retains its charge. Calculate the energy stored in the capacitor if the distance between the plates is now increased to 10.00mm.
Hence account for the difference of your answer in the above two cases.

On the moon, the acceleration due to gravity is 1/6 of Earth's. A ball is thrown straight up on the moon and it takes t = 29 s to return to the surface. What is the difference between the maximum height of the ball thrown on the moon and the ball being thrown on earth?
Is interference a property of some types of waves only or is it a property of all types of waves?
