Chapter 4: 9CP (page 156)

A certain metal with atomic mass 2 × 10^-25 kg has an interatomic bond with length 2.1 × 10^-10 m and stiffness 40 N/m. What is the speed of sound in a rod made of this metal?

Short Answer

Expert verified

V=3500m/s

Step by step solution

Given Information

Most popular questions from this chapter

You hang a mass Mfrom a spring, which stretches an amount $S_{1}$ . Then you cut the spring in half, and hang a mass Mfrom one half. How much does the half-spring stretch? (a) $2 s_{1}$ , (b) $S_{1}$ ,(c) $s_{1} / 2$ .

Suppose that we hang a heavy ball with a mass of 10 kg (about 22 lb ) from a steel wire 3m long that is 3 mm in diameter. Steel is very stiff, and Young’s modulus for steel is unusually large, $2 \times 10^{11} N / m^{2} .$ Calculate the stretch $ΔL$ of the steel wire. This calculation shows why in many cases it is a very good approximation to pretend that the wire doesn’t stretch at all (“ideal non extensible wire”).

A block of one mole of a certain material whose atoms are in a cubic array has dimensions of 5 cm by 4 cmby0.5 cm. What is the interatomic distance?

In a spring-mass oscillator, when is the magnitude of momentum of the mass largest: when the magnitude of the net force acting on the mass is largest, or when the magnitude of the net force acting on the mass is smallest?

Here are two examples of floating objects: (a) A block of wood 20 cm long by 10 cm wide by 6 cm high has a density of 0.7 g/cm³ and floats in water (whose density is 1.0 g/cm³). How far below the surface of water is the bottom of the block. Explain your reasoning?
