Physics homework?
In a resilient environment the resilient mode is E .A longitudinal wave propagates in this environment.(when the wave reaches the distance d the equation is y = Asin ( ωt – φ).
I have to calculate: a). the frequency ν and the wave length
b).the density ρ of the environment
c).the distance d1 between the source and the wave when y= Asin(ωt – φ1)
*Notes: E= 6,75*10^10 N/m^2
d=5 m
ω=10^3Л rad/s
φ=Л rad
φ1=Л/5 rad
Answers for verification: v=500 Hz
φ=2700 kg/m^2
d1=1m
λ=10 m
