For a certain driven series RLC circuit, the maximum generator emf is 156 V and the maximum current is 3.32 A. The current leads the generator emf by 0.959 rad. (a) What is the impedance of the circuit?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
