Question

A heavy rope is suspended from a rigid support. A wave pulse is set up at the lower end, then

Answer 1

answer : The pulse will travel with increasing speed.

explanation : as you know, speed of pulse propagated in a rope is given by, $v=\sqrt{\frac{T}{\mu}}$

where T is tension on rope and $\mu$ is linear mass density .

$\mu$ remains constant for a specific rope.

so, speed of pulse is directly proportional to square root of tension on rope.

due to weight of the rope , the tension will be increasing along the rope from lower end to higher end.

as T is increasing , from above explanatiom speed of pulse must be increasing.

hence, the pulse will travel with increasing speed.

the pulse will travel with increasing speed.
