Given Information:
Stiffness of the metal = s = 45 N/m
Atomic mass of the metal = m = 2.4×10⁻²⁵ kg
Interatomic bond distance = d = 2.4×10⁻¹⁰ m
Required Information:
Speed of sound = v = ?
Answer:
v = 3286.3 m/s
Explanation:
The speed of the sound in a rod made of this metal can be found using the following equation
v = √(s/m)*d
Where s is the stiffness of the metal, m is the atomic mass of the metal, and d is the interatomic bond distance
v = √(45/2.4×10⁻²⁵)*( 2.4×10⁻¹⁰)
v = 3286.3 m/s
Therefore, the speed of the sound in a rod made of this metal would be 3286.3 m/s
