If the gas inside the flask in the above exercise is cooled so that its pressure is reduced to a value of 715.7 torr, what will be the height of the mercury in the open ended arm? (Hint: The sum of the heights in both arms must remain constant regardless of the change in pressure.) (a) 49.0 mm, (b) 95.6 mm, (c) 144.6 mm, (d) 120.1 mm.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
