Two Parallel plates have equal and opposite charges and are seperated by a di-electric 5mm thick of di-electric Constant 3. If the electric intensity in the di electric is 10^6v/m calculate; (A)The free charge per unit area on the conducting plates. (B)The bound change per unit area on the surfaces the di-electric (C)The Polarisation in the dielectric (E) The displacement in the di-Electric (E) The energy density in the dr-Electric ​

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
