-- There is no such thing as the gravity of all the planets. Each
planet has its own number, which is different from any other.
-- Gravity can't be described in units of cm.
Helena af Sandeberg is 170 cm.
Andreas af Enehjelm is 180 cm.
Diamonds specific gravity is 3.52 g/cm
No, there should be an equal mass distribution to have its center of gravity at 50 cm mark
The acceleration due to gravity at sea level at the equator is 32.25744 feet/second2 (983.2186 cm/second2)Formula for your own altitude:Acceleration Due to Gravity (cm/s2) at Altitude (h) = Acceleration Due to Gravity (cm/s2) at Sea Level - 0.3086hwhere h is the altitude in kilometers.
Those completely depend on the scale you choose. Sadly, that important piece of data is not mentioned in the question.
86 cm is a measure of distance or length. It has nothing to do with weight, which is the effect of gravity on a mass.
2.09-2.23g/cm cubed
A cm (centimetre) is a measure of distance, not volume. As a result, there can be no matter inside 1 cm of the mineral.
Betelgeuse has an average surface gravity of 0.0023 m/s2 (0.23 cm/s2), which is about 4261 times less than Earth.
5 cm. But you will not find planets of that size anywhere!
Specific Gravity is unitless. To determine the specific gravity of something you take the density of the substance divided by the density of water (assuming both densities are in the same units ie: g/cm^3, or lb/in^3So for platinum, whose density is 21.45grams/cm^3 you would take (21.45g/cm^3)/(1g/cm^3(this is the density of water)), so specific gravity=21.45This would be the same answer is you had your densities in terms of lbs.
