Two carts, moving at opposite directions, collide and recoil. Which question would help determine if the system of two carts is
open or closed? A) Do the carts have the same mass? B) Do the carts have different initial velocities? ) Is energy transferred from one cart to the other? D) Is the total momentum constant before and after the collision?
It depends on the steady-state frequency. At zero frequency an inductor behaves like an open circuit. As the frequency increases, the inductor acts more like an open circuit and a capacitator acts more like a short circuit
