An atom is made up of three fundamental subatomic particles which are the protons, neutrons and electrons.
- Protons are the positively charged particles. Neutrons do not carry any charges.
- Both protons and neutrons are found in the tiny nucleus at the center of that atom.
- The electrons are negatively charged.
- They are found outside the nucleus in electronic shells.
Acceleration= change in speed/ change in time
30-10= 20 (change in speed)
Time= 10 seconds
20/10= 2
Acceleration= 2 m/s^2
Hope this helps! :)
