Answer:
this data is both accurate and precise
Answer:
0.004012km
Explanation:
Problem:
Conversion of millimeters(mm) to Kilometers:
value given = 4012mm
Here, we are converting from a submultiple unit to a multiple unit.
Millimeter depicts 10⁻³m and kilometer stands for 10³m
Now, we must find how many exponents will take us from 10⁻³ to 10³
careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:
i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³
Therefore,
10⁶mm = 1km
4,012mm = = 0.004012km

If an atom is neutrally charged, then it has the same number of protons and electrones. When the atom loses one or more electrones, the protons are more than the electrones and the atom becomes a positively charged ion.
Henri Becquerel discovered radioactivity and it was the Curies who made experiments about the concept and became known for their d
