Answer:

Ripple marks are caused by water flowing over loose sediment which creates bed forms by moving sediment with the flow. Bed forms are linked to flow velocity and sediment size, whereas ripples are characteristic of shallow water deposition and can also be caused by wind blowing over the surface.

The logarithm of x, written log(x), tells you the power to which you would raise 10 to get x. So, if y=log(x), then x=10^y. It i

Lelechka [254]

Answer:

Explanation:

The function which is inverse to exponentiation is called logarithm.

It is of the form

$log\ x=y\\\Rightarrow log_{10}\ x=y\\\Rightarrow 10^y=x$

The 10 here is the base of the logarithm. The logarithm with base 10 is called common logarithm

$log_{10}1000000=y\\\Rightarrow 10^y=1000000\\\Rightarrow 10^6=1000000\\\Rightarrow y=6$

So, log(1,000,000) = 6

A 40-cm-long tube has a 40-cm-long insert that can be pulled in and out. A vibrating tuning fork is held next to the tube. As th

Umnica [9.8K]

Answer:

The frequency of the tuning is 1.065 kHz

Explanation:

Given that,

Length of tube = 40 cm

We need to calculate the difference between each of the lengths

Using formula for length

$\Delta L=L_{2}-L_{1}$

$\Delta L=74.7-58.6$

$\Delta L=16.1\ m$

For an open-open tube,

We need to calculate the fundamental wavelength

Using formula of wavelength

$\lambda=2\Delta L$

Put the value into the formula

$\lambda=2\times16.1$

$\lambda=32.2\ cm$

We need to calculate the frequency of the tuning

Using formula of frequency

$f=\dfrac{v}{\lambda}$

Put the value into the formula

$f=\dfrac{343}{32.2\times10^{-2}}$

$f=1065.2\ Hz$

$f=1.065\ kHz$

Hence, The frequency of the tuning is 1.065 kHz
