<h2>
Mercury, Neptune, and Jupiter </h2>
Explanation:
- Mercury has the largest semimajor axis that is 5.791 x 107 in km.
- Mercury is the planet with the fastest speed, which has an average orbital speed around the sun for about 47.87 km/s.
- Neptune has the longest orbital speed around the sun of any planet in the Solar System which is equivalent to 164.8 years (or 60,182 Earth days)
- Jupiter has the largest eccentricity.
Hence, the answer is Mercury, Neptune, and Jupiter respectively.
Answer:
The number of O₂ molecules that are left in the cylinder is 1.70x10²⁴.
Explanation:
The number of oxygen molecules can be found using the Ideal Gas law:
Where:
P: is the pressure = 100 psi
V: is the volume = 10 L
n: is the number of moles =?
T: is the temperature = 20 °C = 293 K
R: is the gas constant = 0.082 L*atm/(K*mol)
Hence, the number of moles is:
Now, the number of molecules can be found with Avogadro's number:
Therefore, the number of O₂ molecules that are left in the cylinder is 1.70x10²⁴.
I hope it helps you!
A) This process is only in the research phase.
Explanation:
The process of nuclear fusion is only the research phase.
In nuclear fusion, light atoms combines to form heavier ones with the release of huge amount of energy. Nuclear fusion which is the splitting of heavy unstable nuclides into stable ones also release a large amount of energy.
- Nuclear fission requires a very high activation energy to start with.
- The energy barrier need to start the reaction is very high.
- It occurs at high temperatures and pressure.
- This is not a feasible processes and it is still at its research phase.
- The process occurs naturally in the core of stars
