Answer: The ice cube would float on top of the water and the rock would sink to the bottom.
Explanation: The ice cube has a smaller density than the rock which allows the ice cube to float but makes the rock sink to the bottom of the glass of water.
I believe that this question has the following choices to
choose from:
placer deposits
fossil compaction
hydrothermal solutions
igneous processes
Actually among all, I have never encountered an ore that
formed due to fossil compaction. I suppose we can get minerals such as marble
or lime but not ores. So the answer is:

Determine the speed of the jet
The speed is calculated as:
Substitute 4800 km for Distance and 6hr for Time
<em>Hence, the speed of the commercial jet is 800km/hr</em>
Answer:
B. The same on the moon.
Explanation:
The density of an object is the ratio of the mass contained by the object to the volume occupied by that mass.
When the object is taken from the earth to anywhere in the universe, its mass remains constant. The dimensions of the object and hence its volume also remains constant anywhere in the universe.
Therefore, the density of the object will also remain the same as it depends upon the mass and the volume of the object.
So, the correct option is:
<u>B. The same on the moon.</u>
