Two simple pendulams of lengths 1 and 1.1 m rerspectively start swinging together with the same aplitude. Find the number of swings executed by the longer pendulam before again swing together. [Hint: The longer pendulam will swing more slowely than the shorter. Both will agin begain together after the faster pendulam gains by a complete number of oscillations. Let n be the number of oscillations the longer one makes before they again begain together. therefore (n+x) T_(1)=nT_(2) , where x is the number of oscillations by which the first gains over the second.]
