Explanation:
It is given that there is distance time graph. The slope of any distance time graph will give the speed or velocity of the object.
In the context, it is seen that there is a point in the distance - time graph. And the values of the point in the graph is (4,15).
Now here, the distance is plotted in the ordinate or the vertical y-axis while time is plotted in the abscissa or the horizontal x-axis.
Thus the point (4,15) tells us that the object has traveled 15 units in time equal to 4 seconds.
Answer:
In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is a taxon in the highest rank of organisms, higher than a kingdom. ... The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Bacteria, and Eukaryota domains.
It is about density. The less dense object will tend to float when put into the water. For example, oil is denser than water so the result of the mixture would make oil float. Sinking objects would only mean that it has an equal or greater mass than water.
The argon molecules become solid when the temperature decrease from 20C to -190 C.
<h3>What changes occur in argon?</h3>
The changes in arrangement and movement of the particles of the argon occurs as the temperature of the air decreased because the argon gas begins to freeze. The freezing point of argon is -189 Celsius so when the temperature decrease from 20C to -190 C, the argon molecules becomes solid.
So we can conclude that the argon molecules become solid when the temperature decrease from 20C to -190 C.

The net force on the box is:
50 + 30 - 65
= 15 Newtons
This can be used in conjunction with
F = ma
to calculate the acceleration of the box if its mass is known.
