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 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? If it is\[a\times {{10}^{-2}}\sec \]. Find value of a.
