The Net Force is equal to the mass of the Object multiplied by the amount of Acceleration. Therefore, this creates an equation which looks like this:
F = Mass * Acceleration
F = 2.569 kg * 4.65 m/s
F = 11.95 N

The structural form of the element Ge closely resembles the structure of C (diamond).
Diamond is composed of a lattice structure in which atoms of carbon are held together in a face centered cubic lattice.
Germanium, an element in the same group as carbon also forms a face centered cubic lattice that is very similar to that of diamond.
Hence, the structural form of the element Ge closely resembles the structure of C (diamond).

Answer:
The mass percent of potassium is 39%
Option C is correct
Explanation:
Step 1: Data given
Atomic mass of K = 39.10 g/mol
Atomic mass of H = 1.01 g/mol
Atomic mass of C = 12.01 g/mol
Atomic mass of O = 16.0 g/mol
Step 2: Calculate molar mass of KHCO3
Molar mass KHCO3 = 39.10 + 12.01 + 1.01 + 3*16.0
Molar mass KHCO3 = 100.12 g/mol
Step 3: Calculate mass percent of potassium (K)
%K = (atomic mass of K / molar mass of KHCO3) * 100%
%K = (39.10 / 100.12) * 100%
%K = 39.05 %
The mass percent of potassium is 39%
Option C is correct
