A sturdy steel cable runs from a stake in the ground to the top of a cell tower.
(a)Would you expect the tension in the cable to be the same value at the top of the cable as at the bottom of the cable? Explain.
(b)If a wave is generated at the top of the tower, would you expect it to descend the cable at a constant speed? Explain.
(c)Are waves affected by gravity? Discuss.

A ski gondola is connected to the top of a hill by a steel cable
of length 500 m m and diameter 1.4 cm c m . As the gondola comes to
the end of its run, it bumps into the terminal and sends a wave
pulse along the cable. It is observed that it took 12 s s for the
pulse to return

If you tethered a space station to the earth by a long cable, you could get to space in an elevator that rides up the cable --much simpler and cheaper than riding to space on a rocket. There's one big problem, however: There is no way to create a cable that is long enough. The cable would need to reach 36,000 km upward, to the height where a satellite orbits at the same speed as the earth rotates; a cable...

________ In many cartoon shows, a character runs off a cliff, realizes his predicament, and lets out a scream. He continues to scream as he falls. If the physical situation is portrayed correctly, from the vantage point of an observer at the top of the cliff leaning over the edge, the pitch of the scream as he falls should be A) higher than the original pitch and constant. B) higher than the original pitch and increasing as he falls. C)...
An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
