Answer:

1. Option D) Deciding if the procedure, principles or techniques in question in a forensic case are generally accepted by the relevant scientific community.

2. Option A) thin-layer chromatography

3. Option A) when the jury considers the verdict

Explanation:

1. The Frye Standard is a procedure to determine if the piece of evidence is admissible in a court of law. This is a rigorous test to test how well the evidence can be used against a criminal or prove a case in the court of law. This came after a ruling that an experts advice only was insufficient to prove a case.

2. Thin layer chromatography is used to separate the ink components. This is because the ink is made of different components that have different volatlitities and solublies in the alcohol solution. The inks can be compared by looking at the partitioning coefficient and comparing the two distances traveled by the components.

3. The guilty cannot plead a case when the verdict has been given. At that moment, the case is closed.

If a large housefly 2.4 m away from you makes a noise of 47.0 dB, what is the noise level (in dB) of 5400 flies at that distance
dem82 [27]

Answer:

the noise level of 5400 flies is equal to 84.32 dB

Explanation:

Noise made by house flies = 47 dB from the distance of 2.4 m

to calculate the noise of 5400 flies at a distance of 2.4 m.

the intensity of noise

  10 log_{10}(\dfrac{I}{I_0}) = 47 dB

now,  I' = 5400 I₀

=     10 log_{10}(\dfrac{5400 I}{I_0})

=    10 [log_{10}[5400] +log_{10}(\dfrac{I}{I_0}))      

= 10 ( 3.732 + 4.7 )                            

= 84.32 dB                                          

hence, the noise level of 5400 flies is equal to 84.32 dB

Consider a hydrogen atom in the n = 1 state. The atom is placed in a uniform B field of magnitude 2.5 T. Calculate the energy di
dlinn [17]

Answer:

E=29\times 10^{-5}eV

Explanation:

For n-=1 state hydrogen energy level is split into three componets in the presence of external magnetic field. The energies are,

E^{+}=E+\mu B,

E^{-}=E-\mu B,

E^{0}=E

Here, E is the energy in the absence of electric field.

And

E^{+} and E^{-} are the highest and the lowest energies.

The difference of these energies

\Delta E=2\mu B

\mu=9.3\times 10^{-24}J/T is known as Bohr's magneton.

B=2.5 T,

Therefore,

\Delta E=2(9.3\times 10^{-24}J/T)\times 2.5 T\\\Delta E=46.5\times 10^{-24}J

Now,

Delta E=46.5\times 10^{-24}J(\frac{1eV}{1.6\times 10^{-9}J } )\\Delta E=29.05\times 10^{-5}eV\\Delta E\simeq29\times 10^{-5}eV

Therefore, the energy difference between highest and lowest energy levels in presence of magnetic field is E=29\times 10^{-5}eV
