The statement that is true regarding a distance vs. time graph is option A: The graph should show distance on the vertical axis.
<h3>Where is the plot of distance?</h3>
How far an object has come in a certain amount of time is displayed on a distance-time graph. Time is represented on the X-axis and Distance is plotted on the Y-axis (left) (bottom).
On a distance-time graph, an object's motion is indicated by a sloping line. The slope or gradient of the line in a distance-time graph is equal to the object's speed. The object is travelling more quickly the steeper the line is (and the bigger the gradient).
Note that the distance-time graph shows the relationship between distance and time by plotting distance on the y-axis and time on the x-axis.

Answer:
d. Imaginary point through which the resultant force of gravity acts on an object
Explanation:
Gravity acting on all particle points of the object, no matter how small they are. As a combination, the center of gravity would denote a single point which substitutes for all the gravity forces on the object.

involved in scientific inquiry.
Scientific inquiry refers to an activity of a certain person in where he or she
needs to study a certain thing to be able to get knowledge and understand the
scientific ideas of it on how scientists study it.
Here are the 6 process that are usually involved:
=> asking questions
=> Doing research
=> Make a Hypothesis
=> Testing the hypothesis through experiments
=> analyzing the data and draw a conclusion
=> show your result.</span>
Explanation:
The initial kinetic energy for both blocks is zero. Let and . So using the conservation law of linear momentum, we can write
or
The final kinetic energies for the two masses are
Therefore, the ratio of their kinetic energies is
Enough data points would have been collected when specific data for upward and downward motion are collected.
<h3>
What is a Data point?</h3>
A data point is a discrete unit of information. This information is always unique.
<h3>Free fall</h3>
An object subjected to free fall is under the influence of gravity. An object subjected has different time of motion for upward and downward motion.
Thus, we can conclude that enough data points would have been collected when specific data for upward and downward motion are collected.
