Answer:
1272 pound
Explanation:
From the question given above, the following data were obtained:
Pressure (P) = 38 psi
Area (A) = 12 cm by 18 cm
Force (F) =?
Next, we shall determine the area. This can be obtained as follow:
Area (A) = 12 cm by 18 cm
A = 216 cm²
Next, we shall convert 216 cm² to square inch (in²). This can be obtained as follow:
1 cm² = 0.155 in²
Therefore,
216 cm² = 216 cm² × 0.155 in² / 1 cm
216 cm² = 33.48 in²
Finally, we shall determine the force exerted. This can be obtained as follow:
Pressure (P) = 38 psi = 38 lbf/in²
Area (A) = 33.48 in²
Force (F) =?
P = F/A
38 = F / 33.48
Cross multiply
F = 38 × 33.48
F = 1272 pound
Thus, the force exerted is 1272 pound
this is not my work

My limited understanding is you need pressure, temperature and enough elements that can fuse. If the temperature and pressure aren't high enough and/or you don't have enough elements that can fuse, then no fusion.
In fact I've never heard of fusion in a nebula, only in a star. The exception being a brown dwarf, which is considered substellar at 10 to 90 Jupiters in mass, and they can fuse deuterium (if over 13J) and also lithium (if over 60 J). But the burn through all of it in about 10 million years and wouldn't emit light like a main sequence star would.

Answer:
Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Explanation:
Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron.
