Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
Answer:
1. Newton's First Law of Motion
2.Newton's Third Law of Motion
3.Newton's Third Law of Motion
4.Newton's Second Law of Motion
5.Newton's Third Law of Motion
6.Newton's Second Law of Motion
7.Newton's First Law of Motion
Explanation:
Newton's First Law of Motion states that an object remain at rest or moving with a uniform velocity unless an external force acts on it. This is the law of inertia
Newton's Second Law of Motion states that the force of an objects is the product of mass and acceleration.
Newton's Third Law of Motion states that when two objects interact, a pair of forces act on the objects, and they are equal and act in opposite directions.
Explanation:
Chemical bonding results from attractive forces that joins chemical species.
- Noble gases show no tendency to combine with themselves or with other kinds of atoms because of their completely filled outer energy levels.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels just like the inert gases.
- The stable configuration can be attained by losing or gaining of electrons or sharing of pairs of electrons.
Two examples of how bonds form:
Bonds can be formed by:
- Losing and gaining of electrons to form electrovalent or ionic bonds.
- Sharing of electrons to form covalent bonds.

False not all science experiments are done correctly
Answer:
28 metres
Explanation:
when the bag is about to hit the ground
potential energy = kinetic energy
where m = mass
g = acceleration due to gravity
v = speed
when you simplify the above equation and make v subject of the formular we have
where g = 9.8m/s
h = 40
