Answer:
Time = 8.12 h = 0.34 day
Explanation:
First we find speed of water flow:
Speed = u = (3160 tons/s)(907.185 kg/1 ton)
u = 2866704.6 kg/s
also,
Density = (1 g/mL)(1 mL/1 x 10⁻⁶ m³)(1 x 10⁻³ kg/1 g)
Density = 1000 kg/m³
Now,
Volume Flow Rate = Speed/Density
Volume Flow Rate = (2866704.6 kg/s)/(1000 kg/m³)
Volume Flow Rate = 2866.7 m³/s
Now, we find volume of cylinder:
Volume = (Area)(Length)
Volume = (πd²/4)(L)
Volume = [(π)(0.53 m)²/4][236000 mi][1609.36 m/1 mi]
Volume = 83,792,823.82 m³
Now,
Time = Volume/Volume Flow Rate
Time = (83,792,823.82 m³)/(2866.7 m³/s)
Time = (29299.71 s)(1 h/3600 s)
<u>Time = 8.12 h = 0.34 day</u>
Mechanical waves need mediums. or else it isn't a mechanical wave
<u>Answer:</u> D represents 222, E represents 86, F represents 234 and G represents 90.
<u>Explanation:</u>
The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.
The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.
So, for the chemical equations:
1.
D represents 222, E represents 86.
2.
F represents 234 and G represents 90.
Answer is: The highest occupied s and p sublevels are completely filled.
Noble gases (group 18) are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
Noble gases have very stable electron configuration and does not need to gain electrons, only when they gain energy.
1) For example, krypton is a chemical element with symbol Kr and atomic number 36, which means it has 36 protons and 36 electrons.
Electron configuration of krypton atom:
₃₆Kr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶.
2) Another example, xenon (Xe) is noble gas with atomic number 54, which means it has 54 protons and 54 electrons.
Electron configuration of xenon atom:
₅₄Xe 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶.
Answer:
You could rephrase this to make more sense? You could say “Mary me please!” This is a complete sentence. It has a verb and noun making it a full sentence. “Marry” is your verb and your noun is “me” I hope this helped have a good day! :) Please mark me the brainliest?
