Answer:it’s is part of the cell theory because they where studying cells and to see it you need a microscope
Explanation:basically in the answer area
The answer to that question is c. tamod
Answer:
The air is contained at a high pressure in the tube. When it escapes from a small orifice, it suddenly expands. A large amount of its heat is absorbed in the process of expansion resulting in considerable fall in its temperature. This is why the escaping air feels cold.
Answer:
1. Molecular cloud
2. Close binary
3. Brown dwarf
4. Protostellar wind
5. Thermal pressure
6. Protostellar disk
7. Jet
8. Degeneracy pressure
Explanation:
1. The Sun formed, probably along with other stars, within a large molecular cloud.
2. A Close binary consists of two stars that orbit each other every few days.
3. A Brown dwarf is a "star" so small in mass that its core never gets hot enough to sustain nuclear fusion reactions.
4. Most of the gas remaining from the process of star formation is swept into interstellar space by a protostellar wind.
5. As a protostar's internal temperature increases, its growing thermal pressure helps slow its contraction due to gravity.
6. Planets may form within the protostellar disk that surrounds a forming star.
7. Mass can be lost through a jet of material ejected along a protostar's axis of rotation.
8. A "star" with mass below 0.08 solar mass has its gravitational contraction halted by degeneracy pressure.
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) = <em>130.4 newtons</em> (about 29.2 pounds)
His mass is <em>80 kg</em>. Mass is the thing about him that doesn't change.
He has the same mass on the Earth, on the Moon, or anywhere.
