Standing waves are set up on two strings fixed at each end, as shown in the drawing. The two strings have the same tension and m
uysha [10]

The beat frequency produced by the two standing waves is 13 Hz.

<h3>The wavelength of the shorter string</h3>

The wavelength of the shorter string is calculated as follows;

L = \frac{\lambda}{2} \\\\\lambda = 2L\\\\\lambda = \frac{v}{f} \\\\\lambda = \frac{41.9}{225} \\\\\lambda = 0.186 \ m\\\\\lambda = 18.6 \ cm\\\\L= \frac{\lambda }{2} \\\\L = \frac{18.6 \ cm}{2} = 9.3\ cm

<h3>The length of the longer string</h3>

L_2 = 0.58 \ cm \ + 9.3 \ cm\\\\L_2 = 9.88 \ cm \\\\\lambda _2 = 2L_2\\\\\lambda _2 = 2(9.88 \ cm)\\\\\lambda_2 = 19.76 \ cm = 0.1976 \ m

The frequency of the longer string is calculated as follows;

v_1 = v_2\\\\f_2 = \frac{v_2}{\lambda_2} \\\\f_2 = \frac{41.9}{0.1976} \\\\f_2 = 212 \ Hz

<h3>Beat frequency</h3>

The beat frequency produced by the two standing waves is calculated as follows;

F_b = 225 \ Hz \ - \ 212 \ Hz\\\\F_b = 13 \ Hz

Which land feature is formed by two oceanic tectonic plates diverging? *
qaws [65]

Answer:

mid-ocean ridge

Explanation:

When two oceanic tectonic plates diverge, it means they pull away from each other. When this happens, new land is created where the two plates moved apart.

Sense an ion is an atom does it have a negative charge?
IRINA_888 [86]
Ions are the name for atoms that have gained or lost one or more electrons, leaving them with a net charge. For atoms that lose an electron, they gain a positive charge and become cations. For atoms that gain an electron, they take on a net negative charge and become anions.
