In a certain rlc circuit, a 32-ω resistor, a 18-mh inductor, and a 5-µf capacitor are connected in series with an ac power source for which vrms = 16 v and f = 100 hz.

(a) calculate the amplitude of the current,
(b) calculate the phase between the current and the voltage,
(c) calculate the maximum voltage across each component

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
