Could I have help with question 1? 

Problem 1. A string on the violin has a length of 24.5 cm and a mass of 0.86 g. The fundamental frequency of the
string is 1 kHz. (a) What is the speed of the wave on the string? (b) What is the tension in the string? (490 m/s, 843 N)
Problem 2. You aim a high-speed camera at a string tensioned to 910 N, while a sinusoidal wave travels along the
string. The camera shows that 91 wave cycles pass by a given point in 0.39 seconds, and the distance between
consecutive wave crests is 0.57 meters. What is the string's linear mass density in kg/m? (0.0514 kg/ m)
