Q. A satellite circles planet Roton every 2.3 h in an orbit having a radius of 1.2 ´ 107 m. If the radius of Roton is 5.0 ´ 106 m, what is the magnitude of the free-fall acceleration on the surface of Roton?
Q. Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 respectively and released. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do the angular frequencies of the three pendulums compare?
a. w3 > w2 > w1
b. Need to know amplitudes to answer this question.
c. Need to know to answer this question.
d. w1 > w2 > w3
e. w1 = w2 = w3
