Answer : The frequency of violet light is 7.32\times 10^{19}s^{-1}

Explanation : Given,

Wavelength of violet light = 4.10\times 10^{-12}m

Formula used :

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

where,

\nu = frequency of light

\lambda = wavelength of light

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

Now put all the given values in the above formula, we get:

\nu=\frac{3\times 10^8m/s}{4.10\times 10^{-12}m}

\nu=7.32\times 10^{19}s^{-1}

Therefore, the frequency of violet light is 7.32\times 10^{19}s^{-1}

Frequency = speed of light/wavelength 
speed of light = ~ 3 x 10^8 m/s.

If the relative rate of diffusion of ozone as compared to chlorine is 6:3 and further if the density of chlorine is 36 Find out
Alexandra [31]

Answer:

The density of ozone is 4.24.

Explanation:

The relation between the relative rate of diffusion and density is given by :

r\propto \dfrac{1}{\sqrt d}

The given ratio of the relative rate of diffusion of ozone as compared to chlorine is 6:3.

Let the density of ozone is d₂.

\dfrac{r_1}{r_2}=\sqrt{\dfrac{d_2}{d_1}} \\\\\dfrac{6}{3}=\sqrt{\dfrac{d_2}{36}} \\\\3=\dfrac{\sqrt{d_2}}{6}\\\\d_2=\sqrt{18} \\\\d_2=4.24

So, the density of ozone is 4.24.

lana [24]

Answer:

active transport

Explanation:

Active transport -

It refers to the movement of the molecules from a region of lower concentration towards a region of higher concentration via a membrane , is referred to as active transport.

The process of active transport need to have some cellular energy .

Hence,

The concentration of potassium is maintained in the red blood cells via the process of active transport.

Description of the process of coffee turning into water?
xeze [42]

Answer:

In this process, the coffee beans are soaked in caffeine-free green coffee extract, allowing the caffeine to be extracted from the bean and into the solution while the flavor components are retained in the beans. The Swiss Water Process results in coffee that is 99.9% caffeine-free.

Explanation:

Coffee: Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffee species. When coffee berries turn from green to bright red in color – indicating ripeness – they are picked, processed, and dried. Dried coffee seeds are roasted to varying degrees, depending on the desired flavor.

Water: Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
