Option a. The total force that is calculated is given as 24 n/s
<h3>How to solve for the magnitude</h3>
300 g = 0.3kg
Force = change in momentum / time
We have to find the mass x velocity
0.3 x 40 = 12kg m / s
This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.
Force 1 x 12
= 12 N
The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.
The total force that is exerted would be calculated as 12N + 12N = 24 N/S

Three equally spaced points ( . . . ) often used to represent an omission of words in a quotation are best known as ellipsis. They are also known as ellipsis dots, suspension points, or simply ellipsis.
<h3>Usage</h3>
"For example, I may be writing an article to be published in a journal and not include ellipsis. . ."
In summary, we utilise ellipsis to indicate that a list goes on beyond those items actually spelled out in the text.

The theory of plate tectonics cannot be used in explaining: the origin of the Earth's core.
<h3>What is a tectonic plate?</h3>
A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that comprises two (2) plates:
- Continental plates
- Oceanic plates
<h3>The theory of plate tectonics.</h3>
The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.
<h3>The uses of the theory of plate tectonics.</h3>
- It can be used to explain the presence of magnetic anomalies on the ocean floor.
- It can be used to explain the geographical distribution of earthquakes and volcanoes.
- It can be used to explain the presence of glacial deposits in tropical areas.
- It can be used to explain the origin of mountains.
