What is the speed of transverse waves in the wire : A variable-length air column is placed just below a vibrating wirethat is fixed at both ends. The length of the air column open at one end is graduallyincreased from zero until the first position of resonance isobserved at L = 34.0 cm.

How long does it take the swimmer to cross the river : A swimmer, capable of swimming at a speed of 0.8 m/s in still water (i.e., the swimmer can swimwith a speed of 0.8 m/s relative to thewater), starts to swim directly across a 3.0 km wide river. However, the current is 0.91 m/s,and it carries the s..
