A sound wave in air at 20 Celsius has a frequency of 151 Hz and a displacement amplitude of 5.40×10-3 mm. Part A For this sound wave calculate the pressure amplitude (in Pa).
Use 1.42×105 Pa for the adiabatic bulk modulus.
Pmax= 2.11 Pa
Part B Find the intensity of the wave
Use 1.20 kg/m^3 for the density of air.
I=?

the answer is d

explanation:

dan realized that his goal of going to an ivy league school if only he works hard which means basically this   to become completely aware of (something) as a fact; understand without a doubt to make (something desired or anticipated) occur to give real, definite or physical form to a plan, dream, or goal to earn (money or a profit) from a deal

this is poiselle's equation from fluid mechanic in physics. mech eng
