2) a) A tube consists of two pipes, one just slightly smaller thanthe other, that can slide in and out like a telescope. Each pieceis approximately 35cm long. A tuning fork is held at one end as onetube is slid into the other. The apparatus is heard to resonate atvarious total lengths, which are recorded in the table below.Discuss which harmonics these are and whether the pipe likely to besealed at the opposite end. Sketch these harmonics. Also determinethe frequency of the tuning fork. [Note: The studentâs measurementsare close, but might not be precise.] Make sure you state theevidence for your conclusions.
Lengths (cm)

b) A variety of strings are seen to vibrate as seen below. Someends are fixed in place and some are free to slide along a rigidrod. The lengths, masses and tensions are given. Rank theseaccording to the frequency of the oscillation. (Least togreatest)
L=40cm, m=10g, FT=100N L=30cm, m=20g, FT=150N
L=40cm, m=20g, FT=150N L=30cm, m=20g, FT=100N

One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts at a 27.2o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.

The second force has a magnitude of 6.00 N and acts at a 57.6o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.
