<span>F = m.a
= mass x acceleration
So,
a = F / m
Where,
F is coulomb repulsion.
k q q / r^2
with,
k = 9 x 10^9 in SI units (q in C and r in m)
Hence,

Answer:
4.64E14
Explanation:
First convert 645 nm to m = 6.4500E-7m. The equation for finding v with these values is the speed of light/wavelength. so 2.998E8/6.4500E-7m.
so your v or frequency would equal 4.64E14
Fun fact you know this is visible light because the visible light range is within the E14 range.
Answer: Atoms contain tiny, negatively charged electrons
Explanation: Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles.
A single ringed nitrogeo base is thymine (C)
Answer:
The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.
