A metal bar with a length of 1.80 m has a density of 6200 kg/m3. Longitudinal sound waves travel from one end of the bar to the other in a time interval of 4.50×10−4 s. What is Young's modulus for this metal? Express your answer in pascals.

A P-wave from an earthquake travels at a speed of 13 km/s through the Earth's inner core. The density of the kg inner core is about 13- cm3 13000 , close to that of mercury. From the speed of a P wave, determine the bulk m3 modulus of the inner core material in units of N = Pa. Remember, you are squeezing rock! m2 O 1.3 × 104 O 2.2 x 1012 O 7.7 × 10–5 O 1.7 × 108 none of these.

An Ethernet cable is 4.30 m long. The cable has a mass of 0.205 kg. A transverse pulse is produced by plucking one end of the taut cable. The pulse makes four trips down and back along the cable in 0.795 s. What is the tension in the cable?

A certain metal with atomic mass 2.3∗10-25 kg has an interatomic bond with length 2.4∗10-10 m and stiffness 42 n/m. What is the speed of sound in a rod made of this metal?

(a) An ethernet cable is 4 m long and has a mass of 0.25 kg. A transverse wave pulse is produced by plucking one end of the taut cable. The pulse makes 5 trips down and back along the cable in 0.5 s. What is the tension in the cable? (b) A simple pendulum consists of a ball of mass 3 kg hanging from a uniform string of mass 0.06 kg and length L. If the period of oscillation of the pendulum is 3 s, determine the speed of a transverse wave in the string when the pendulum hangs vertically.

The windpipe of one typical whooping crane is 5.5 feet long. What is the fundamental resonant frequency of the bird's trachea, modeled as a narrow pipe closed at one end? (Assume a temperature of 34°C.)

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 9 km/s. Estimate the average bulk modulus of Earth's crust given that the density of rock is about 2100 kg/m3. Pa

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
