Answer:

Explanation:

Brownian motion is a random (irregular) motion of particles e.g smoke particle. The set up in the diagram can be used to observe the motion of smoke.

1. The apparatus used are:

A is a source of light

B is a converging lens

C is a glass smoke cell

D is a microscope

2. The uses of the apparatus are:

A - produces the light required to so as to see clearly the movement of the particles.

B - converges the rays of light from the source to the smoke cell.

C - is made of glass and used for encamping the smoke particles so as not to mix with air.

D - is used for the clear view or observation or study of the motion of the smoke particles in the cell.

Calculate the The wavelength of the first Balmer series of hydrogen is 6562 following: a) The ionization potential, and b) The f

postnew [5]

Answer:

(a) 13.6 eV

(b) 10.2 V

Explanation:

a) Ionization potential energy is defined as the minimum energy required to excite a neutral atom to its ionized state i.e basically the minimum energy required to excite an electron from n=1 to infinity.

Energy of a level, n, in Hydrogen atom is, $E_{n}=-\frac{13.6}{n^{2} }$

Now ionization potential can be calculated as

$E_{\infty}- E_{0}$

Substitute all the value of energy and n in above equation.

$=-\frac{13.6}{\infty^{2}}-(-\frac{13.6}{1^{2}})\\=13.6eV$

Therefore, the ionization potential is 13.6 eV.

b) This is the energy required to excite a atom from ground state to its excited state. When electrons jumps from ground state level(n=1) to 1st excited state(n=2) the corresponding energy is called 1st excitation potential energy and corresponding potential is called 1st excitation potential.

So, 1st excitation energy = E(n 2)- E(n = 1)

$=-\frac{13.6}{2^{2}}-(-\frac{13.6}{1^{2}})\\=-3.4eV - (-13.6eV) \\=10.2eV$

Now we can find that 1st excitation energy is 10.2 eV which gives,

$eV'=10.2eV\\V'=10.2V$

Therefore, the 1st excitation potential is 10.2V.

In a series circuit,what is the same in each circuit element

GuDViN [60]

The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.
