Answer:
4 times the mass of Earth
Explanation:
= Mass of Earth
= Mass of the other planet
r = Radius of Earth
2r = Radius of the other planet
m = Mass of object
The force of gravity on an object on Earth is
The force of gravity on an object on the other planet is
As the forces are equal
So, the other planet would have 4 times the mass of Earth
The reason a location usually doesn't get a storm within a few weeks of another one is more because of the general odds. They're low. And they're lower in Texas than in Florida. ... There are many locations a storm can develop and track

Answer:
The energy levels are: 3s and 3p
Explanation:
<u>The sodium (Na) element, with atomic number 11 (number of protons: Z=11), has the next electronic configuration</u>:
Z=11: 1s² 2s² 2p⁶ 3s¹ = [Ne] 3s¹
<u>Hence, the electricity used in a sodium vapor lamp will</u> excite the electron of the energy state n=3 from the s-orbital to the next highest energy p-orbital <u>which then</u> drops back to the lower energy s-orbital by the emission of a photon <u>resulting in the production of light</u>.
<u />
<u>The transition of the electron is</u>:
Excitation: [Ne] 3s¹ → [Ne] 3s⁰ 3p¹
Emission: [Ne] 3p¹ → [Ne] 3s¹
So, the energy levels that are involved in the process are 3s and 3p.
Have a nice day!
