Answer:
A) a chain reaction that is caused by nuclear fission
Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth
Newton's Second law of motion states that "<em>the </em><em>acceleration</em><em> of an object depends upon </em><em>two</em><em> </em><em>variables</em><em> – the net force acting on the object and the mass of the object.</em>"
In our case the mass of the book and the force of gravity

<span>Answer: option (4) the same magnitude and the opposite sign.
</span>
Justification:
<span /><span /><span>
</span><span>1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals).
</span>
<span /><span /><span>
2) Protons are positive particles that are inside the nuclus of the atom.
</span><span />
<span>3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom.
</span>
<span /><span /><span>
4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign: (+) + (-) = 0: positive + negative = neutral.</span>
