Answer:
atoms
Explanation:
Hormones are derived from amino acids or lipids. Amine hormones originate from the amino acids tryptophan or tyrosine. Larger amino acid hormones include peptides and protein hormones. Steroid hormones are derived from cholesterol.
KE = ½m*v² = ½*1.0*[0.866*3E8]² = 3.375E16 J
<span>Etot = mc²/√[1 - (v/c)²] = 1.8E17 J</span>
There's nothing on the list you provided that's related to Coulomb's Law.
