A "seconds pendulum" is one that moves through its equilibrium position once each second. (The period of the pendulum is precisely 2.000 s.) The length of a seconds pendulum is 0.9927 m at Tokyo and 0.9949 m at Cambridge, England. What is the ratio of the free-fall accelerations at these two locations?
(g Cambridge / g Tokyo) = __________
In the figure, two particles, each with mass m = 0.82 kg,are fastened to each other, and to a rotation axis at O,by two thin rods, each with length d = 5.7 cm and massM = 1.4 kg. The combination rotates around the rotationaxis with angular speed ω..
