Answer:
The 10 kg rock has more inertia than the other two rocks.
Explanation
The speed of sound depends on the medium in which it is transported.
Sound travels fastest through solids, slower through liquids and slowest through gases.
So it will travel slowest through water at 55 degrees

We need to extrapolate the altitude from the graph. To do this we can write an equation that describes the line, then any point not shown on the graph can be found. The linear graph is in the form of y=mx+b. The slope, m, (rise/run) can be found from the two points as
m= (567K - 147.54K)/(78.11km - 18.4km) = 7.02495.
Now to get the y intercept, b, we can use this slope and the x and y values from one of the data points given into the y=mx+b equation:
147.54 = 7.02495(18.4) + b
and then solve for b with:
147.54 = 129.259 + b
18.2808 = b
Now our equation is
y = 7.02495x + 18.2808
y is the temperature, x is the depth. Now solve the original question:
601 = 7.02495x + 18.2808
582.719 = 7.02495x
582.719/7.02495 = x
x = 82.95km
It lasts 29 1/2 days.
-the sidereal month- is the true period of the moon's revolution around Earth. It lasts 27 1/3 days.
-the difference of 2 days between the synodic and sidereal cycles is due to the Earth- moon system also moving in an orbit around the sun.
