A simple instrument for measuring the acceleration of gravity employs a linear spring from which a mass is suspended. At a location on earth where the acceleration of gravity is $32.174\ \mathrm{ft} / \mathrm{s}^2$, the spring extends $0.291\ \mathrm{in}$. If the spring extends $0.116$ in. when the instrument is on Mars, find the Martian acceleration of gravity. How much would the spring extend on the moon, where $\mathrm{g}=5.471\ \mathrm{ft} / \mathrm{s}^2$?

At a location on Earth where the acceleration of gravity is $32.174\ \mathrm{ft} / \mathrm{s}^2$, the spring extends $0.291\ \text{in.}$ If the spring extends $0.116\ \text{in.}$ when the instrument is on Mars. what is the Martian acceleration of gravity? How much would the spring extend on the moon, where $\mathrm{g}=5.471\ \mathrm{ft} / \mathrm{s}^2$ ?

In listening to a concert, you attend to the solo instrument and perceive the orchestra as accompaniment. This illustrates the organizing principle of a. figure-ground. b. shape constancy. c. grouping. d. depth perception.

The $\mathrm{A}$ string of a violin is $32$ cm long between fixed points with a fundamental frequency of $440 \mathrm{~Hz}$ and a linear density of $5.5\times10^{-4}$ kg/m. (a) What are the wave speed and tension in the string? (b) What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also $440 \mathrm{~Hz}$ if the speed of sound is $343$ m/s in air?
(c) What is the frequency of the first overtone of each instrument?

The instrument package shown in Fig. $5.18$ weighs $258 \mathrm{~N}$. Determine the tension in the cable if the package is completely submerged in seawater having a specific weight of $10.05\ \mathrm{kN} / \mathrm{m}^3$.

Suppose you want to determine the electric field in a certain region of space. You have a small object of known charge and an instrument that measures the magnitude and direction of the force exerted on the object by the electric field. How would you determine the magnitude and direction of the electric field if the object were (a) positively charged and (b) negatively charged?

The object has a charge of $+ 20.0 \mu C$ and the instrument indicates that the electric force exerted on it is $40.0 \mu N$ due east. What are the magnitude and direction of the electric field?

F. an instrument for measuring rainfall

G. the standard writing system in present-day Korea

I. a turtle ship

By what fraction will the frequencies produced by a wind instrument change when air temperature goes from $10.0^{\circ} \mathrm{C}$ to $30.0^{\circ} \mathrm{C}?$ That is, find the ratio of the frequencies at those temperatures.

If a wind instrument, such as a tuba, has a fundamental frequency of 32.0 Hz, what are its first three overtones? It is closed at one end. (The overtones of a real tuba are more complex than this example, because it is a tapered tube.)
