P2.8 A tuning fork is struck generating a sound which results in a 22nd harmonic standing wave in a 90cm tube which is open at both ends. This same tuning fork simultaneously creates a 19th harmonic standing wave in a tube which is closed at one end. Determine the length of the closed tube.
A sound wave travels through a solid copper cylinder that has radius of 1.29x10-3m, and length L=10.0m, and mass m=0.468kg. Copper has a Young's modulus of 1.10x10-11N/m2. How long does it take the sound wave to travel from one end of the cylinder to the other?

Another student uses the launcher to consecutively launch several
spheres that have the same diameter but different masses, one after
another. Each sphere is launched from position A. Consider each
sphere’s launch speed, which is the speed of the sphere at the
instant it loses contact with the plate. On the axes below, sketch
a graph of launch speed as...
At one instant, the center of mass of a system of two particles is located on the x-axis at x = 2.0 m and has a velocity of (5.0 m/s ) i^. One of the particles is at the origin. The other particle has a mass of 0.10 kg and is at rest on the x-axis at x = 8.0...
1.) A _____ magnetic field can create an electric current. A.Perpendicular B.Changing C.Dipole D.Strong
There are a lot of numbers in this problem. Just about the only way to get it right is to work out each step symbolically first, and then plug numbers into the final symbolic result. Two coils of wire are aligned with their axes along the z-axis, as shown in the diagram. Coil 1 is connected to a power supply...
What errors could have impacted the qualitative behavior (i.e., the shape) of our electric field lines of the dipole and of the set of parallel plates? (Hint: what makes electric fields? How could such things have been present in the ambient environment?) Suppose you swapped positive and negative charges in the dipole arrangement. What would happen to the electric field...
Two parallel long (infinite for our purposes) wires are oriented
along the z-axis. The figure below shows the
(xy)-plane perpendicular to the wires, including
the positions where the wires cross this plane. The wires carry
some unknown electric currents I1 and
I2, which you need to find from a
single measurement of the magnetic field
