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

A string or rope will break apart if it is placed under too much tensile stress. Thicker ropes can withstand more tension without breaking because the thicker the rope, the greater the cross-sectional area and the smaller the stress. One type of steel has density 7870 kg/m³ and will break if the tensile stress exceeds 7.0 x 108 N/m². You want to make a guitar string from a mass of 4.5 g of this type of steel. In use, the guitar string must be able to withstand a tension of 900 N without breaking. Your job is the following. Express your answer in meters.

By what percentage does the density of water increase at a depth of 1.25 km below the surface? Bulk modulus of water is 220 * 10 ^ 9 Pa. Density of water is 100 * 10 ^ 3 * ka / (m ^ 3)

Problem Solving... A torsion test shows that the shear modulus of an aluminum specimen is 4.60 x 10^6 psi. When the same specimen is used in a tensile test, the modulus of elasticity is found to be 12.2 x 10^6 psi. Find Poisson's ratio for the specimen. O 0.33 O 0.40 O 0.95 O 0.30 Вack Next Clear form

A cylindrical specimen of some metal alloy of 8 mm in diameter is stressed elastically in tension. A force of 15700 N produces the elastic modulus of 138 GPa of the specimen, the longitudinal strain is: O a. 2.26 O b. 2.23 O c. 2.28 O d. 2.29

I need a proper solution for these questions ( well explained and understandable writing)  What is Faraday's second law of electromagnetic induction? and what is an induced emf?

4. Under certain conditions, wind blowing past a rectangular speed limit sign can cause the sign to oscillate with a frequency w (see Fig.). Assume that w is a function of the sign width, b; sign height, h; wind velocity, V; air density, p; and an elastic constant, k, for the supporting pole. The constant, k, has dimensions of Nm. (a) Develop a suitable set of pi terms for this problem using b, V, and p as repeating variables. (b) List all the other possible combinations of repeating variables that could have been utilized for this problem. SPEED LIMIT 40
