A mixture is 2 or more different elements not bonded together
Example : N2 or O2
Answer:
Explanation:
For n-=1 state hydrogen energy level is split into three componets in the presence of external magnetic field. The energies are,
,
,
Here, E is the energy in the absence of electric field.
And
are the highest and the lowest energies.
The difference of these energies
is known as Bohr's magneton.
B=2.5 T,
Therefore,
Now,
Therefore, the energy difference between highest and lowest energy levels in presence of magnetic field is
Answer:
The value of the distance is .
Explanation:
The velocity of a particle(v) executing SHM is
where, is the angular frequency, is the amplitude of the oscillation and is the displacement of the particle at any instant of time.
The velocity of the particle will be maximum when the particle will cross its equilibrium position, i.e., .
The maximum velocity() is
Divide equation (1) by equation(2).
Given, and . Substitute these values in equation (3).
Answer: its a strip of transparent film, one side coated with gelatin emulsion containing microscopically small light-sensitive silver halide crystals
Explanation:
