Tamsen and Vera imagine visiting another planet, planet X, whose gravitational acceleration, gx, is different from that of Earth's. They envision a pendulum, whose period on Earth is 2.243 s, that is set in motion on planet X, and the period is measured to be 1.380 s. What is the ratio of gx/9Earth? Neglect any effects caused by air resistance. 9x = 2.2 X GE Your response differs from the correct answer by more than 10%. Double check your calculations. If the average density of planet X is equal to Earth's average density, PE, what is the ratio of RX/RE, where RE is the mean radius of Earth? (Assume both planets are spherical. Recall that p = m/V and Vsphere = r.) Rx = 1/1 RE Your response differs from the correct answer by more than 10%. Double check your calculations.
