A horizontal wire has one end fastened to a wall while the other
end is pulled with a force of 200 N. The wire has a length of 5 m,
a volume mass density of 7,000 kg/m3 , and a resistivity
of 6.9e-07 Ωm. A transverse pulse takes 0.2 s to travel the length
of the wire. Calculate the electrical power dissipated by the wire
while a current of 2 A is passing through the wire.

A ball is attached to one end of a wire, the other end being
fastened to the ceiling. The wire is held horizontal, and the ball
is released from rest (see the drawing). It swings downward and
strikes a block initially at rest on a horizontal frictionless
surface. Air resistance is negligible, and the collision is
elastic. The masses of the ball and block are, respectively, 1.6 kg
and 2.3 kg, and the length of the wire is 1.21 m....

One end of a very long wire is rigidly fastened to a post. The
other end is attached to an audio speaker which shakes the end of
the wire in a direction perpendicular to its length. The wire has a
diameter 1.1 mm , a volume mass density of 7800
kg/m3, and is held under a
tension of 6.7 N. The speaker creates a wave on the wire with an
amplitude 0.56 cm and a frequency of 65.0 Hz ....

A 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall.
Part AA 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. The mass is pulled away from the equilibrium position (x = 0) a distance of 17.5 cm and released. It then oscillates in simple harmonic motion with a frequency of 8.38 Hz. At what position, measured from the equilibrium position, is the mass 2.50 seconds after it is released?–5.23 cm16.6 cm–5.41 cm–8.84 cm–11.6 cm Part BA 23.3-kg...
