<span>Momentum, a quantity of motion of a moving body, is mathematically defined as mass x velocity. Hence the magnitude of momentum of a 25-kg mass traveling at 40 m/s is 40x25 = 1000 kg-m/s. As momentum is directional in nature, momentum = (1000i + 0j + 0k) kg-m/s in vector notation (as body is traveling east)</span>

Momentum is the product of speed/velocity and the mass of a body in motion. The momentum of a body at rest is zero since its speed is also zero. In this case, the mass is 25 kg while the velocity is 40 m/s.
Therefore, momentum = mass x velocity
= 25 × 40
= 1000 kgm/s

Show that the entire Paschen series is in the infrared part of the spectrum. To do this, you only need to calculate the shortest

mr_godi [17]

Answer and Explanation:

The computation of the shortest wavelength in the series is shown below:-

$\frac{1}{\lambda} = R(\frac{1}{n_f^2} - \frac{1}{n_i^2} )$

Where

$\lambda$ represents wavelength

R represents Rydberg's constant

$n_f$ represents Final energy states

and $n_i$ represents initial energy states

Now Substitute is

$1.097\times 10^7\ m^{-1}\ for\ R, \infty for\ n_i,\ 3 for\ n_i,\\\\\ \frac{1}{\lambda} = R(\frac{1}{n_f^2} - \frac{1}{n_i^2} )$

now we will put the values into the above formula

$= 1.097\times 10^7 m^{-1}(\frac{1}{3^2} - \frac{1}{\infty^2} )\\\\ = 1.097\times10^7\ m^{-1} (\frac{1}{9} )$

$= 1218888.889 m^{-1}$

Now we will rewrite the answer in the term of $\lambda$

$\lambda = \frac{1}{1218888.889} m\\\\ = 0.82\times 10^{-6} m$

So, the whole Paschen series is in the part of the spectrum.

Will an atom emit light if all the atoms electrons are in the ground state

Oliga [24]

No,

To emit light an electron has to jump down to a lower energy level but in an electron is unable to go any lower in ground state.
