Answer:
True
Explanation:
In the first step of coal making all the plant species and trees which start decaying, gets buried under the earth crust and lead to the formation of peat. The peat is further acted upon by the heat and pressure thereby leading to the formation of lignite coal (soft brown coal), which further turns into bituminous coal (black and brittle) and then get converted into anthracite (highest carbon content and is found at greatest depth)

Answer:
The correct answer is 0.47 m³
Explanation:
The formula for density (d) is
Mass (m) ÷ volume (v)
Hence
d = m ÷ v
The density of aluminium (as provided in the question) is 2700 kg/m³ and the mass of aluminium is 1280 kg, the volume is however unknown.
Thus, from the formula earlier
2700 = 1280 ÷ v
v = 1280 ÷ 2700
v = 0.47 m³
The volume of aluminium when the density is 2700 kg/m³ and the mass is 1280 kg is 0.47 m³
Answer:
volume = 0.47 .
Explanation:
Density:
We have that d = 2700 kg/ and that we have 1280 kg of Al.
V = 0.47
The apparent brightness of a star depends on how bright it really IS, and also on its distance from Earth. Just like matches, flashlights, and fireflies, stars that are closer to us look brighter to us. (Think about the Sun.)
