In an rc series circuit, ℰ = 17.0 v, r = 1.60 m, and c = 1.80 µf.
(a) calculate the time constant. 2.88 s
(b) find the maximum charge that will appear on the capacitor during charging. 30.6 µc
(c) how long does it take for the charge to build up to 12.0 µc? 1.434 s

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
