In physiotherapy ultrasound with frequency f = 1000 kHz and intensity I = 1 W/cm2 is used. Find amplitude of tissue molecules vibration under the action of this ultrasound wave. The density of tissue is p = 1050 kg/m3 and speed of ultrasound propagation in the tissue v = 1550 m/sec.

Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). The P-waves have a speed of about 6 km/s. Estimate the average bulk modulus of Earth's crust given that the density of rock is about 2,800 kg/m3. Got 1.008 or 1.008 x 1011 Pa prior and said it was incorrect
