Neutral Magnesium atom
Explanation:
From the given description of the atom, one can infer that this atom is a neutral atom.
In a neutral atom, the number of protons and neutrons are the same.
Atomic number = 12
Mass number = 25
This atom is Magnesium.
Magnesium has an atomic number of 12 from the periodic table.
Number of protons = 12 = atomic number
Number of electrons = 12(for neutral atoms, atomic number is same as number of electrons).
Number of neutrons = mass number - atomic number = 25-12 = 13.

Answer:
= 308.5 N
Explanation:
acceleration of rocket for safe landing
= initial velocity
=final Velocity
m = mass of rocket
-5.625 
Upward force
F - mg = ma
F = ma+ mg
F = m(a+g)
m= mass
a = 5.625
g = 9.8
= 20(5.625 + 9.8)
= 308.5 N
