Explanation:
An atom is made up of three fundamental particles:
- Protons are positively charged particles in an atom
- Electrons are negatively charged.
- Neutrons carry no charges.
In a neutral atom, the number of protons and electrons are the same and equal.
Most atoms are usually depicted this way:
ᵃₙX
where a is the mass number of the atom.
n is the atomic number
X is the symbol of the atom
The mass number is the sum of the number of protons and neutrons
Atomic number is the number of protons.
In a neutral atom, the atomic number is also the number of electrons since the atom is neutral. It has not gained or lost any additional electrons.

Number of protons = atomic number (12)
Mass Number = 0.25
mass number = number of protons + number of neutrons
Number of neutrons = mass number - number of protons
Number of neutrons = 0.25 - 12
number of neutrons = - 11.75

Answer:
Work, W = F * d, and
Work = change in kinetic energy, so W=deltaKE.
Hence,
deltaKE=F * d
(1/2)*m*v^2 =F * d
d=[(1/2)*m*v^2]/F
d=[(1/2)*0.6*20^2]/5
d=24 m.
Explanation:
Work = change in kinetic energy, so W=deltaKE.
