What do halo stars do differently from disk stars?

Physics
1 answer:
VLD [36.1K]3 years ago
6 0

Answer: They orbit the galactic center with many different inclinations, while disk stars all orbit in nearly the same plane. ... They have vertical motions out of the plane, making them appear to bob up and down, but they never get "too far" from the disk.

What is the maximum wavelength of light capable of removing an electron from a hydrogen atom in the energy states characterized
Reil [10]

To solve this problem we will apply the Rydberg formula is used in atomic physics to describe the wavelengths of the spectral lines of many chemical elements.

This equation is given in its general form as,

\Delta E = -R_H (\frac{1}{n_1^2}-\frac{1}{n_2^2})

Here,

R_H = Rydberg constant for Hydroge is approximately 2.178*10^{18} J

n_1= Principal quantum number of an energy level

n_2= Principal quantum number of an energy level for the atomic electron transition

PART A ) For n=1 we have that

\Delta E = -R_H* \frac{1}{n^2}

\Delta E = -2.178*10^{-18}*\frac{1}{1^2}

\Delta E = -2.178*10^{-18}J

Now calculating the wavelength using following equation

\lambda = \frac{hc}{\Delta E}

Here

h = Planck's constant

c = Speed of light

\lambda = \frac{(6.626*10^{-24})(2.9979*10^8)}{2.178*10^{-18}}

\lambda = 9.120*10^{-8}m = 91.2nm

PART B) For n = 3 we have that

\Delta E = -R_H *\frac{1}{n^2}

\Delta E = -2.178*10^{-18}*\frac{1}{3^2}

\Delta E = -2.42*10^{-19}J

Now calculating the wavelength using following equation

\lambda = \frac{hc}{\Delta E}

\lambda = \frac{(6.626*10^{-24})(2.9979*10^8)}{2.42*10^{-19}}

\lambda = 8.208*10^{-7}m = 820.8nm

Which equation represents mass-energy equivalence? E = m2c E = mc2 E = (mc)2 E = mc
motikmotik

Einstein's energy mass equivalence relation say that if the whole given mass is converted to energy then it would be

E = mc^2

where

m = mass in kg

c = speed of light in m/s

this is the origination of quantum physics and by this formula we can relate the dual nature of light and particle

So correct relation above will be

E = mc^2
