If a longitudinal wave passes a specific point seven times per second, and the distance between wave rarefaction points is 2 met

zavuch27 [327]

Answer: 14 m/s

Explanation:

The speed $S$ of a sound wave is given by the following equation:

$S=\lambda f$

Where:

$\lambda=2 m$ is the wavelength of the sound wave

$f=7 times/s=7 Hz$

$S=(2 m)(7 Hz)$

Hence:

$S=14 m/s$

In 1977 off the coast of Australia, the fastest speed by a vessel on the water

fenix001 [56]

Answer: 154.08 m/s

Explanation:

Average acceleration $a_{ave}$ is the variation of velocity $\Delta V$ over a specified period of time $\Delta t$ :

$a_{ave}=\frac{\Delta V}{\Delta t}}$

Where:

$a_{ave}=1.80 m/s^{2}$

$\Delta V=V_{f}-V_{o}$ being $V_{o}=0$ the initial velocity and $V_{f}$ the final velocity

$\Delta t=85.6 s$

Then:

$a_{ave}=\frac{V_{f}-V_{o}}{\Delta t}}$

Since $V_{o}=0$ :

$a_{ave}=\frac{V_{f}}{\Delta t}}$

Finding $V_{f}$ :

$V_{f}=a_{ave} \Delta t$

$V_{f}=(1.80 m/s^{2})(85.6 s)$

Finally:

$V_{f}=154.08 m/s$
