A string of length 40 cm and weighing 10...

A string of length 40 cm and weighing 10 g is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of `160 N m^-1` and is stretched by 1.0 cm. If a wave pulse is produced on the string near the wall, how much time will it take to reach the spring ?

To solve the problem step by step, we will calculate the time taken for a wave pulse to travel along the string from the wall to the spring. ### Step 1: Convert Units First, we need to convert the given measurements into consistent units. The length of the string is given as 40 cm, which we can convert to meters: \[ L = 40 \text{ cm} = 0.40 \text{ m} \] The mass of the string is given as 10 g, which we can convert to kilograms: ...

The pulse is symmetric about its maximum which is located at a distance of 20 cm from the end joined to the ring. (a) Assuming that the wave is reflected from the ends without loss of energy, find the time taken by the string to regain its shape. (b) The shape of the string changes periodically with time. Find this time period. (c) What is the tension in the string ?
