Answer:
yes ,what's the question
and if the question is why
then it's for gravity
The speed of the runner is 300 m /38 seconds. You can simplify this answer to be about 7.9 m/s
Velocity is defined as Distance divided by Time.
In other words, V = D/T.
Now that we have our formula, we can solve.
Let's plug in the numbers we have.
We have 12m [East (direction not necessary when solving yet)] for our distance, and 0.15s as our time.
Divide the distance (12 /) by the time (0.15)
12 / 0.15 = 80.
Your velocity is 80 m/s [E]
I hope this helps!
Answer:

Explanation:
density of the solid box material = 
density of the liquid material = 
Given that
solid box floats with two thirds of its volume submerged in a liquid
let V be the volume of the box
then,

⇒
so, the ratio of densities of solid and and the liquid is 2/3
