The answer must show the lowest number of significant number of significant places in the decimal region

Explanation:

5.67 + 0.00032 adds up to 5.67 because the least number of significant figures in the decimal place 2.

To add up two numbers, that are in decimal places.
Identify the number of significant figures in them
Their addition should sum up to a value no more than the significant figures to the right of the decimal having the lowest accuracy.

5.67

+ 0.00032

to the right of the decimal, they have two significant numbers.

The answer should also be this way.

Which two subatomic particles have the greatest mass?

denpristay [2]

Answer:

PROTON AND NEUTRON

Explanation:

The mass of proton is : $1.67*10^{-27}kg$

A proton is one of the main particles that make up the atom . The other two particles are neutron and electron. Protons are found in the nucleus of the atom.This is a tiny , dense region at the centre of the atom. Protons have a positive charge of one (+1) and a mass of 1 atomic mass unit ( amu ) , which is about $1.67*10^{-27}kg$ . Together with neutrons , they make up virtually all of the mass of an atom.

The mass of neutron is also approximately: $1.67*10^{-27}kg$ but a little more than that .

Atoms of all elements - except Hydrogen , have neutrons in their nucleus . Unlike protons and electrons , these have no charge - they are electrically neutral . The mass of a neutron is slightly greater than the mass of a proton but not very significant
