<h3>NET FORCE </h3>
The net force is equal to the sum of two forces acting in the same direction on an object. The net force is always bigger than the individual forces in this scenario.
Answer:
Covalent Bond
Explanation:
Covalent Bonds happen when elements in a compound share electrons to exist together in a stable state as in the diagram
Answer:
Sample Response: The LED lightbulb is the most energy efficient because it loses the least amount of energy as heat.
Answer: Energy is released by the electron in the form of light
Explanation:
Let's start by explaining that each atom in its natural state has a specific structure of its energy levels. Where <u>the lowest energy level is called the </u><u>ground state</u><u>. </u>
<u>
</u>
So, when an atom is in its ground state, its electrons fill the lower energy orbitals completely before they begin to occupy higher energy orbitals.
Then, when an atom is excited, it means that it has left its ground state (in which each electron occupies its place in its orbit, around the nucleus), when this happens some electron jumps out of the orbit it occupied in its fundamental state to an outer orbit, further away from the nucleus <u>and then return to the ground state, emitting in the form of light the energy received.</u>
To understand it better:
An excited electron is an unstable electron, and when passing from one orbit to another, it produces light of a specific wavelength (color) that depends on the amount of energy the electron loses.
Answer:
Actually the formulae is S=(u+v/2)t
.TO explain,from average velocity=distance /time
and average velocity is u+v/2
hence using the formular
Average velocity=distance/time
distance will be=average velocity ×time
so S=(u+v/2)t
