What is the wavelength if the frequency is 29.2 hz?

ZanzabumX [31]

Answer : The wavelength is $1.027\times 10^7m$

Solution : Given,

frequency = 29.2 Hz

Formula used :

$\nu=\frac{c}{\lambda}\\\lambda=\frac{c}{\nu}$

where,

$\nu$ = frequency

$\lambda$ = wavelength

c = speed of light = $3\times 10^8m/s$

Now put all the given values in this formula, we get the wavelength.

$\lambda=\frac{3\times 10^8m/s}{29.2Hz}=0.1027\times 10^8m=1.027\times 10^7m$ $(1Hz=1s^{-1})$

Therefore, the wavelength is $1.027\times 10^7m$

Mixtures can be separated into their components by taking advantage of differences in the chemical properties of the components.

Sedaia [141]

The method of separating mixtures by means of their differences in the chemical properties of the components is less convenient because these methods requires reactions therefore needs energy, increasing the costs for the process.

Which of the following items is a salt? (1 point)

Tems11 [23]

Calcium carbonate is the salt among the given options.

Calcium carbonate ( CaCO3) can be regarded as which appears as white and odorless powder or as a colorless crystals it is insoluble in water.

The chemical formula is CaCO3. It can be used as an antacid as well as food colouring and a food firming agent and a fertilizer.

Calcium carbonate is calcium salt as well as carbonate salt with one-carbon compound

Salt can be regarded as substance which is produced by reaction between acid and base. It consists negative ion (anion) of that acid as well as positive ion (cation) of the base.

Sodium hydroxide is a base and not a salt

Carbonic acid is an acid and not a salt

Therefore, calcium carbonate is the only salt in the among the given options.
