Answer:

Pressure = Force/Area

347 = 1300/Area

Area = 1300/347

area= 3.47m2

The wavelength of the visible line in the hydrogen spectrum that corresponds to m = 5 in the Balmer equation is: A. 656 nm. B. 4
BaLLatris [955]

Answer:

The wavelength of the visible line in the hydrogen spectrum is 434 nm.

Explanation:

It is given that, the wavelength of the visible line in the hydrogen spectrum that corresponds to n₂ = 5 in the Balmer equation.

For Balmer series, the wave number is given by :

\dfrac{1}{\lambda}=R(\dfrac{1}{n_1^2}-\dfrac{1}{n_2^2})

R is the Rydberg's constant

For Balmer series, n₁ = 2. So,

\dfrac{1}{\lambda}=1.097\times 10^7\times (\dfrac{1}{2^2}-\dfrac{1}{5^2})

\lambda=4.34\times 10^{-7}\ m

or

\lambda=434\ nm

So, the wavelength of the visible line in the hydrogen spectrum is 434 nm. Hence, this is the required solution.

Why-does-the-energy-of-a-sound-wave-decrease-over-time
KengaRu [80]
The sound wave never actually loses energy, the bulk of energy it had at the beginning of the sound, is spread out into a sphere, making it decrease in amplitude and frequency.

marshall27 [118]

Answer:

C. Copper

Explanation:

F = Force on string

L_0 = Intial length of string

A = Area of string

E = Young's modulus of material

Change in length is given by

\Delta L=\frac{FL_0}{AE}

It can be seen that the change in length is inversely proportional to the Young's modulus of the material.

Here

E_a=0.7\times 10^{11}\ Pa

E_b=0.91\times 10^{11}\ Pa

E_c=1.1\times 10^{11}\ Pa

\\\Rightarrow E_c>E_b>E_a

So, copper will stretch the least.

How did the process of outgassing help shape Earths atmosphere?
Nana76 [90]

Answer:

Earth's first atmosphere 4.6 billion years ago was most likely comprised of hydrogen and helium (two most abundant gases found in the universe!)

Through the process of outgassing, the outpouring of gases from the earth's interior, many other gases were injected into the atmosphere. These include:

-water vapor (produced rain - rivers, lakes, oceans)

-carbon dioxide

-nitrogen

As outgassing occurred over a period of millions of years, the atmosphere evolved to its current state
