CHOOSE ANSWER Speed
is a measurement of the rate of change of CHOOSE ANSWER

speed
with respect to time. The speed of an object is the CHOOSE ANSWER
the object travels per unit of CHOOSE ANSWER
. Because the speed of most moving objects is not constant, we frequently calculate the CHOOSE ANSWER
speed of an object as it travels. Average CHOOSE ANSWER
is calculated by CHOOSE ANSWER
the total CHOOSE ANSWER
an object traveled by the total amount of CHOOSE ANSWER
it took the object to travel that distance (s = d/t).

Because you ate playdough

The process is c.convection

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
