Answer:
D. Atoms are like solid balls
Explanation:
John Dalton proposed that all matter is composed of very small things which he called atoms. This was not a completely new concept as the ancient Greeks (notably Democritus) had proposed that all matter is composed of small, indivisible (cannot be divided) objects. When Dalton proposed his model electrons and the nucleus were unknown.
Answer:
Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules. There are three main classes of biopolymers, classified according to the monomers used and the structure of the biopolymer formed: polynucleotides, polypeptides, and polysaccharides.
Explanation:
Answer:
Wavelength = 0.06024 m
Explanation:
Equation of energy of wavelength from Einstein's relativity equation is;
E = hc/λ
Where;
h is Planck's constant = 6.626 × 10⁻³⁴ J. s
c is speed of light = 3 × 10⁸
We are given E = 3.3 × 10^(-24) J
Making wavelength λ the subject, we have;
λ = hc/E
Thus;
(6.626 × 10⁻³⁴ × 3 × 10⁸)/(3.3 × 10^(-24)) = 6.024 × 10^(-2) = 0.06024 m
Wavelength = 0.06024 m
