In the flow past a compression corner, the upstream Mach number and pressure are 3.5 and 1 atm, respectively. Downstream of the
yulyashka [42]

Answer:

\theta=23.7^{\circ}

Explanation:

The ratio of pressure 2 to 1 us 5.48/1= 5.48 rounded off as 5.5.

Referring to table A.2 of modern compressible flow then M_{\beta_1}=2.2

Also

M_{\beta_1}=M_1 sin \beta and making sin\beta the subject of the formula then

sin\beta=\frac {2.2}{3.5}\\\beta=38.94^{\circ}

Making reference to \theta-\beta-M diagram then

\theta=23.7^{\circ}

The balmer series is formed by electron transitions in hydrogen that
RSB [31]

Answer:

The Balmer series refers to the spectral lines of hydrogen, associated to the emission of photons when an electron in the hydrogen atom jumps from a level n \geq 3 to the level n=2.

The wavelength associated to each spectral line of the Balmer series is given by:

\frac{1}{\lambda}=R_H (\frac{1}{2^2}-\frac{1}{n^2})

where R_H is the Rydberg constant for hydrogen, and where n is the initial level of the electron that jumps to the level n = 2.

The first few spectral lines associated to this series are withing the visible part of the electromagnetic spectrum, and their wavelengths are:

656 nm (red, corresponding to the transition 3 \rightarrow 2)

486 nm (green, 4 \rightarrow 2)

434 nm (blue, 5 \rightarrow 2)

410 nm (violet, 6 \rightarrow 2)

All the following lines lie in the ultraviolet part of the spectrum. The limit of the Balmer series, corresponding to the transition \infty \rightarrow 2, is at 364.6 nm.

What happens when a continental plate splits apart
Tatiana [17]
When plates pull apart underwater, the hot magma instantly rises and spreads itself to form a new ocean floor.Under a continent, the crust splits open to allow magma out. The magma might make its way slowly to the surface, creating warm areas and hot springs or geysers as surface water meets it.<span>Or the magma might explode, bringing into existence a new volcano where there was only cool earth before.</span>

7 Consider two homogeneous bodies of
kupik [55]

Answer:

No, it is not necessary for them to have same mass.

Explanation:

Let both bodies have a density d1 and d2 respectively.

Since their volumes are equal V1 = V2

we know that,

density = \frac{mass}{volume}

Hence, d1 = \frac{m1}{V1} and d2 = \frac{m2}{V2}  

Taking the ratio of densities,we get

\frac{d1}{d2} = \frac{m1}{m2}

This implies that unless the bodies have same densities, the mass of the two bodies will not be same.
