Answer:
Rust is a compound. What makes iron rust is its reaction with oxygen and moisture in the air.
Explanation:
mg = kx
k = mg/x
k = 0.40(9.8)/0.030
k = 130.66666...
k ≈ 130 N/m
350.72 m/s
Formula for velocity of wave is;
v = fλ
Where;
v is speed
f is frequency
λ is wavelength
We are given;
f = 512 Hz
λ = 0.685 m
Thus;
v = 512 × 0.685
v = 350.72 m/s
