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 7,600 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, 1.7 kg and 2.4 kg, and the length of the wire is 1.13 m....

One end of a light uniform rod is attached to a wall by a frictionless hinge. The rod is held in a horizontal position by a wire that runs from the other end of the rod to the wall. The wire has length 2.00m and makes an angle of 30.0∘ with the rod. A block with mass m is suspended by a light rope attached to the middle of the rod. The transverse fundamental standing wave on the wire has...

One end of a 75-cm long horizontal wire is fixed and the other end passes over a pulley that supports a 450-N weight. The linear density of the wire is 0.00500 kg/m. A vibrating tuning fork placed near the wire causes the wire to vibrate in its 1st overtone. The vibrating tuning fork is then placed near an adjustable pipe closed at one end and causes the air column in the pipe to vibrate in its first overtone. (a) what...

A horizontal spring with spring constant 2 N/m has one end connected to a wall while the other end is connected to a block resting on a frictionless surface. The mass of the block is 0.5 kg. The block is pulled 10 cm away from its equilibrium position and released. (a) Calculate the frequency of the resulting simple harmonic motion. (b) Calculate the maximum velocity of the block When the mass is 3 cm away from equilibrium it then strikes...

Two wires are parallel, and one is directly above the other. Each has a length of 38.6 m and a mass per unit length of 0.0267 kg/m. However, the tension in wire A is 47.3 × 102 N, while the tension in wire B is 1.50 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much...
