Weight = (mass) x (acceleration of gravity at the place where the mass is) .
Man's mass = 80 kg
His weight on Earth = (80 kg) x (9.8 m/s²) = 784 newtons (about 176 pounds)
His weight on the Moon = (80 kg) x (1.63 m/s²) = 130.4 newtons (about 29.2 pounds)
His mass is 80 kg. Mass is the thing about him that doesn't change.
He has the same mass on the Earth, on the Moon, or anywhere.
7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed _______ the conglomerate.
8. Geologists use the principle of _______ to justify using fossils in a sample of sedimentary rock to determine the rock’s age.
9. Partings between adjacent beds of sedimentary rock may represent periods of _______, which could range from a few decades to a few centuries.
10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means _______ material is at the top instead of at the bottom.

Answer:
Explanation:
5. Limestone typically doesn't accumulate in the ocean at depths below 4,000 meters because below that depth, calcite is ___not preserved ____.
The calcite compensation depth CCD is the depth at which the rate of dissolution of calcite increases beyond that of accumulation.
6. Based on the principle of original horizontality, geologists conclude that layers of sedimentary rock that have been tilted must have been subjected to __tectonic forces_____.
Tectonic forces causes changes in a particle terrain
7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed __earlier than_____ the conglomerate.
The principle of inclusion states that the inclusion is older than the rock that contains it.
8. Geologists use the principle of __fossil and fauna succession _____ to justify using fossils in a sample of sedimentary rock to determine the rock’s age.
The principle of fossil and fauna succession was credited to Williams Smith and it is used for relative dating of a sedimentary sequence. Here, fossils of plants and animals are used to date a sequence.
9. Partings between adjacent beds of sedimentary rock may represent periods of __unconformity _____, which could range from a few decades to a few centuries.
An unconformity is a period of non-depsotion or erosion within a rock layer.
10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means ___the oldest____ material is at the top instead of at the bottom.
From the principle of superposition of strata, we know that the oldest layer is at the bottom of the sequence and the youngest is on top.

Wave frequency is the number of waves that pass a fixed point in a given amount of time.
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

Final answer:
The object's density is calculated by dividing its mass (10 grams) by its volume (5 cubic centimeters), yielding a density of 2 g/cm³.
Explanation:
The density of an object is calculated by dividing its mass by its volume. For the object in question, its mass is 10 grams and its volume is 5 cubic centimeters. Therefore, you would calculate density as follows: Density = Mass / Volume. Plug in the values and you get: Density = 10 grams / 5 cubic centimeters. This equals 2 g/cm³. Hence, the density of the object is 2 grams per cubic centimeter.
