In the experiment for determining the velocity of propagation of a pulse in a
slinky, we prefer a long slinky/string
a) because pulse cannot be formed in a short slinky/string
b) because slinky/string is cheap
c) so that pulse may move through it easily
d) so that time taken by pulse to move from one end of slinky/string to other is more

Answer:
The correct answer is option (d).
Explanation:
A longer string is preferred as the speed of the pulse generated is quite high which makes it difficult to measure the time taken in a single turn.
Therefore, a longer string is used so that the pulse created takes more time to travel from one end of the string to the other end such that measurements can be taken easily.
