As the captain of the scientific team sent to Planet Physics, one of your tasks is to measure g�. You have a long, thin wire labeled 1.54 g/mg/m and a 1.24 kgkg weight. You have your accurate space cadet chronometer but, unfortunately, you seem to have forgotten a meter stick. Undeterred, you first find the midpoint of the wire by folding it in half. You then attach one end of the wire to the wall of your laboratory, stretch it horizontally to pass over a pulley at the midpoint of the wire, then tie the 1.24 kgkg weight to the end hanging over the pulley. By vibrating the wire, and measuring time with your chronometer, you find that the wire's second harmonic frequency is 200 HzHz. Next, with the 1.24 kgkg weight still tied to one end of the wire, you attach the other end to the ceiling to make a pendulum. You find that the pendulum requires 316 ss to complete 200 oscillations. Pulling out your trusty calculator, you get to work.What value of g will you report back to…

I am very confused because I was taught that for a series, you would calculate it by adding C1+C2+C3...etc and for parallel, you would calculate it by doing 1/Ctot=1/C1+1/C2+1/C3...etc. but it seems as if you have it the other way around.
