Answer:

22.7 meters

Explanation:

Let's remind the difference between distance and displacement:

- distance: the total distance travelled by an object in all its paths

- displacement: the different between the final and initial position of the object

In this case, the problem asks to find the distance covered by the ball. This will be the sum of the distances covered by the ball in each part of its motion, therefore:

d=13.2 m+9.5 m=22.7 m

(instead, the displacement will be the difference between the final and initial position of the ball, therefore:

d=13.2 m-9.5 m=3.7 m)

Which function is decreasing?
tangare [24]
The function which is decreasing is C. <span>Air pressure in the earths atmosphere as a function of altitude.
The higher you go, the less air pressure there is because of the fewer air molecules at such altitudes. 
This means that the remaining functions are either constant or increasing. </span>

Usually, when the temperture is increased l, what will happen to the ratevof dissolving?
pochemuha
<span>When temperature is increased, the rate of dissolving increases. The kinetic energy of the molecules of the solute and solvent molecules is high thereby increasing their contact. An example is mixing powdered sugar to the water. When you add water to the sugar, the dissolving process is slow. However, when you increase the temperature of the water by boiling it, the sugar dissolves immediately. </span>

_________ acceleration occurs when an object speeds up.
Angelina_Jolie [31]

Positive acceleration occurs when an object speeds up.

Explanation:

Acceleration is the rate of change in velocity per unit time:

a=\frac{\Delta v}{\Delta t}

where \Delta v is the change in velocity while \Delta t is the time interval. From the formula, we can understand that when \Delta v is positive, so when the object is speeding up, the acceleration is positive; on the contrary, when \Delta v is negative (so, when the object is slowing down), the acceleration is negative.
