A transverse wave is traveling along a string of total mass M, length L, and tension T. Which of the following is correct? a. The wavelength of the wave is proportional to L. b. The wave velocity depends on M,L,and T. c. The frequency of the wave is proportional to the wavelength. d. The speed of motion of a point on the string is the same as the velocity of propagation of the wave.
A string of length L is connected between two supports such that it has a tension T, and the speed of a transverse wave on the string is c. A second string with length 2L has the same total mass as the first string, and is tensioned with a force of 2T. What is the speed of a transverse wave on the second string?
an
ice puck of mass m revolves on an icy surface in a circle at speed
v at the end of a horizontal string of length L. the tension in the
string is T.
write the equation for centripetal force, and substitute the
values T and L appropriately. then with a bit of elementary
algebra, rearrange the equation so that it solves for mass.
find the mass of the puck when the length of the string is 2.0
m, string...
A block of mass M is suspended by a massless wire of length L and, after a completely inelastic collision with a bullet of mass m, swings up to a maximum height y < L. Find: (a) the speed v of the block with the bullet in it immediately after impact; (b) the tension force T in the wire immediately after impact; (c) the initial horizontal velocity vo of the bullet. Explain pendulum tension please.

A rod uniform and homogeneous AB of length L=4.00 m is attached
to a wall as shown and secured via a massless rope BC of length
l=5.00 ml=5.00 m to the wall (see Fig. 4). A mass M1=40.0 kg is
attached to the rod at B. The rod itself has a mass M=2.00 kg.
