A uniform string of length 'L' is suspended from a point on the ceiling. A small wave pulse is now introduced at its lowest end and it starts moving up towards the ceiling.
(i) What will be the speed of the wave pulse when it has moved up a distance x?
(ii) How much time does this wave pulse take to reach the ceiling?

Explanation

To solve the problem step by step, we will address each part of the question separately.

### Part (i): Speed of the Wave Pulse at Distance x

1. **Understanding the Setup**:
- We have a uniform string of length \( L \) suspended from a ceiling. A wave pulse is introduced at the lowest end and travels upwards.

2. **Identifying Relevant Variables**:
