A wire of length 50 cm and weighing 10 gm is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 50 N/m and is stretched by 1 cm. If a wave pulse is produced on the string near the wall, then how much time will it take to reach the spring?

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 ?

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 ?

A string of length 10.0 m and mass 1.25kg stretched with a tension of 50N. If a transverse pulse is created at one end of the string, how long does it take to reach the other end ?

A spring of spring constant 5 xx 10^(3) N//m is stretched initially by 5 cm from the unstretched position. The work required to further stretch the spring by another 5 cm is .

A spring of spring constant 5 xx 10^(3) N//m is stretched initially by 5 cm from the upstretched position. The work required to further stretch the spring by another 5 cm is .

A body of mass 0.4 kg is held between two massless springs whose ends are fixed to rigid walls as shown in the figure. The spring constants are 8 N/m and 2 N/m. If the body is displaced along the direction of the lengths of the springs and released, the time period (in second) of the oscillations will be (ignore vertical oscillation, if any )
