Answer:
198.2m/s
Explanation:
Speed of a wave(v) is the product of the frequency of the wave (f) and its wavelength(¶).
Mathematically, v = f/¶
Given frequency of the middle C = 261.63Hz
Wavelength = 131.87cm
Converting this to meters we have;
131.87/100 = 1.32m
Speed of the sound = 261.63/1.32
Speed of the sound = 198.20m/s
Therefore the speed of sound for middle C is 198.2m/s
The stretching force acting on the second wire, given the data is 588 N
<h3>Data obtained from the question</h3>
- Radius of fist wire (r₁) = 3.9×10⁻³ m
- Force of first wire (F₁) = 450 N
- Radius of second wire (r₂) = 5.1×10⁻³ m
- Force of second wire (F₂) =?
<h3>How to determine the force of the second wire</h3>
F₁ / r₁ = F₂ / r₂
450 / 3.9×10⁻³ = F₂ / 5.1×10⁻³
cross multiply
3.9×10⁻³ × F₂ = 450 × 5.1×10⁻³
Divide both side by 3.9×10⁻³
F₂ = (450 × 5.1×10⁻³) / 3.9×10⁻³
F₂ = 588 N
