A ball rolls 12 meters in 4 seconds.What is the average speed of the ball?

Chemistry
1 answer:
Degger [83]3 years ago
7 0

Answer:

3 meters/second

Explanation:

Speed is roughly defined as distance travelled over a unit of time. So we can calculate the speed of the ball using the formula:

s=\dfrac{d}{t}

where:

s = speed

d = distance

t = time

Given:

d=12 meters

t = 4 seconds

So we plug that in our equation:

s=\dfrac{d}{t}

s=\dfrac{12meters}{4seconds}

s=3\dfrac{meters}{second}

At a high concentration do you have more or less particles per unit volume
Whitepunk [10]

Answer:

More particles per unit volume

Explanation:

Concentration means the amount of solute in a solution. Now, the amount of solute also means the number of particles of solute present in a solution.

Hence, when we use the term "high concentration", we imply that the amount of solute present or the number of particles present in a solution is high.

Thus, at high concentration, there are more solute particles than solvent particles in a solution.
