Note: I'm not sure what do you mean by "weight 0.05 kg/L". I assume it means the mass per unit of length, so it should be "0.05 kg/m".
Solution:
The fundamental frequency in a standing wave is given by
where L is the length of the string, T the tension and m its mass. If we plug the data of the problem into the equation, we find
The wavelength of the standing wave is instead twice the length of the string:
So the speed of the wave is
And the time the pulse takes to reach the shop is the distance covered divided by the speed:

Answer:
Explanation:
Calculate the volume of the lead
Now calculate the bouyant force acting on the lead
This force will act in upward direction
Gravitational force on the lead due to its mass will act in downward direction
Hence the difference of this two force
If V is the volume submerged in the water then bouyant force on the bobber is
Equate bouyant force with the tension and gravitational force
Now Total volume of bobble is
=
