Expand each vector into their component forms:
Similarly,
Then assuming the resultant vector is the sum of these three vectors, we have
and so has magnitude
and direction such that
The atomic mass of an atom (in amu) is equal to
2 answers:
Answer:
the total number of its protons and neutrons
Explanation:
An atom is represented by
here we know that
z = atomic number
it represent the total number of protons or total number of electrons present in an neutral atom
A = mass number
it represents the total number of neutrons and protons present inside the nuclei of an atom
this is also known as atomic mass of an atom in amu (atomic mass unit)
