Need to know to answer thisquestion.
w1 >w2 > w3
w1 =w2 = w3 Three pendulums with strings of the same length and bobs of thesame mass are pulled out to angles q1,q2 and q3 respectively andreleased. The approximation sin q = q holds forall three angles, with q3 >q2 > q1. How do theangular frequencies of the three pendulums compare? w3 >w2 > w1 Need to knowamplitudes to answer this question. Need to know to answer thisquestion. w1 >w2 > w3 w1 =w2 = w3

Explanation / Answer

Since the approximation sinq = q   holds, then the ang freq only depends on length. . Since they all have the samelength,     w1 = w2 = w3
