Answer:Stirring.

Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.

Answer:

There is at least one instant which instantaneous acceleration is equal to average acceleration. $a = 1500\,\frac{km}{h^{2}}$ .

Explanation:

The average acceleration experimented by the car is:

$\bar a = \frac{85\,\frac{km}{h} - 35\,\frac{km}{h} }{\frac{2}{60}\,h }$

$\bar a = 1500\,\frac{km}{h^{2}}$

According to the Rolle's Theorem, there is at least one instant t so that instantaneous acceleration equal to average acceleration for the analyzed interval. That is to say:

$v'(c) = \frac{v(\frac{2}{60} )-v(0)}{\frac{2}{60}-0}$

If car is accelerating at constant rate, instantaneous acceleration coincides with average acceleration for all instant t. Then, instantaneous acceleration is:

$a = 1500\,\frac{km}{h^{2}}$

How does a distance-time graph show you which direction the runner is moving? Use your own words and science vocabulary.

Dmitry [639]

In a distance time graph, when the x and y values are positive (in first quadrant), the runner is moving forward.

While, if the distance value ( in the y axis) is negative, the runner is moving backwards ( towards the start) .

Hope it helps :)
