It seems that you have missed the necessary details for us to answer this question, so I had to look for it. Anyway, here is the answer. If the US <span>adopted and maintained a policy of minimal control of co2 emissions, the level that we would expect its emissions to be in 2020 is that WE CAN'T TELL FROM THIS DATA. Hope this helps.</span>
Answer:
The answer is B, to convert kelvin to temperature you :
Subtract 273 (k - 273)
<u>Answer:</u> The correct answer is saturated solution.
<u>Explanation:</u>
For the given options:
Dilute solutions are defined as the solutions in which solute particles are present in less very amount than the solvent particles.
Unsaturated solutions are defined as the solutions where more and more of solute particles can be dissolved in the given amount of solvent.
Saturated solutions are defined as the solutions where no more solute particles can be dissolved in the solvent. The concentration of the solute particles that can be dissolved in a solution is maximum.
Supersaturated solutions are defined as the solutions where more amount of solute particles are present than the solvent particles.
From the above information, we conclude that the given solution is saturated solution.
Answer:
The wave's frequency is <u><em>733 hertz</em></u>.
Explanation:
The wavelength (λ) is the minimum distance between two points of the wave that are in the same state of vibration.
Frequency (f) is the number of vibrations that occur in a unit of time.
The speed of propagation (v) is the speed with which the wave propagates in the middle. Relate wavelength (λ) and frequency (f) inversely proportionally using the following equation: <em>v = f * λ</em>.
In this case you know that:
- Wavelength of the sound wave (λ) = 0.450 meters
- Speed of the sound wave (v)= 330 meters per second= 330
Replacing you get:
Then:
f=733.33 hertz≅733 hertz
Finally, <u><em>the wave's frequency is 733 hertz.</em></u>
