Which forensic scientist is, in part, responsible for the very specific evidence collection guidelines that exist in an effort t
Agata [3.3K]

D.) Edmond Locard. He formulated the basic principle that there will be a transfer of material if one object touches another. This material may contaminate a specimen and make it useless as forensic evidence.

“A.) Leone Lattes” is <em>incorrect</em>. He developed a method for <em>blood typing</em> that relied on detection of the specific antibodies.

“B.) Mathieu Orfila” is <em>incorrect</em>.  He worked to make <em>chemical analysis</em> a routine part of forensics.

“C.) Hsi Duan Yu” is <em>incorrect</em>. It is a 13th century Chinese <em>book </em>that many people consider to be the first known guide to forensic pathology.

Nuclear physicists have discovered over 100 different particles that compose the nucleus of an atom. From a chemistry perspectiv
Julli [10]

Answer:

Protons and neutrons which packed tightly into central core of the atom.

Explanation:

Atoms are composed of three subatomic particle; electron, proton and neutron. Electrons are negatively charged, protons are positively charged whereas neutrons are neutral, hence does not have any charge.

Out of three, protons and neutrons are present in the nucleus of the atom.

Nucleus is the central part of the atom possessing most of the mass of the atom. In the nucleus, protons and neutrons are tightly packed with the help of nuclear force.

Electrons are present around the nucleus also called electron cloud.

Therefore, nucleus are composed of protons and neutrons which packed tightly into central core of the atom

Answer

7665 years

Procedure

Let N₀ be the amount of carbon-14 present in a living organism. According to the radioactive decay law, the number of carbon-14 atoms, N, left in a dead tissue sample after a certain time, t, is given by the exponential equation:

N = N₀e^(-λt)

where λ is the decay constant which is related to half-life (T1/2) by the equation:

\lambda=\frac{ln(2)}{t_{\frac{1}{2}}}

Here, ln(2) is the natural logarithm of 2.

The percent of carbon-14 remaining after time t is given by N/N₀.

Using the first equation, we can determine λt.

The half-life of carbon-14 is 5,720 years, thus, we can calculate λ using the second equation, and then find t.

\lambda=\frac{ln(2)}{5720}=1.211\times10^{-4}

Solving the second equation for t, and using the λ we have just calculated we will have

t= 7665 years
