.15 km. It goes in this way from largest to least: Kilometers, Hectometers, decameters, meters, decimeters, centimeters, and finally millimeters. When you are going up in measures you move the decimal point one space to the left for each measure you pass. It is vice-versa for going down these measures plz mark brainliest.
I am pretty sure it’s all the above
The answer would be erin out of all of them thank me later :)
Answer:

Explanation:
The gravitational potential energy of an object is defined as:

where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object above a reference level (usually, the ground)
For the boulder in the problem,
m = 1000 kg
g = 10 N/kg
h = 6 m
Substituting,

Answer:
that the sun has sunspots, which appear to be dark in color. Galileo's discoveries about the Moon, Jupiter's moons, Venus, and sunspots supported the idea that the Sun - not the Earth - was the center of the Universe, as was commonly believed at the time.
