For the most part aesthetics but you could argue they reduce air turbulence in some cases which would lead to better gas mileage. On sports cars however the goal is usually down force which is not wanted on economy cars as it can actually worsen gas mileage.
I hope that answered your question.
Answer:
B. The width of a door
Explanation:
The width of a door is closest to 1 meter in length
The answer is:
when Bohr's original model stated that electrons were tiny little objects circling the nucleus along fixed orbits, however, this is no longer valid as we now know that rather "circling" the nucleus at confined orbits, electrons can seem to be everywhere at once
.
-So, The correct answer for this question would be QUANTIZATION OF ENERGY. The aspect of Bohr's original model of electron structure that is still included in the currently accepted theory of electron structure is the quantization of energy.
-Bohr suggested circular orbits of electrons around the nucleus of a hydrogen atom, but researches have shown that motion of the electron is not in a single plane., but it takes place in three-dimensional space. Actually, the atomic model is not flat

Answer:
F = 268 Hz
Explanation:
The beat frequency is given as:
|
So, for the first flute and tuning fork:
where,
F = Frequency of tuning fork
F = 248 Hz ± 20 Hz
F = 268 Hz (OR) 228 Hz
Now, for the second flute and tuning fork:
where,
F = Frequency of tuning fork
F = 288 Hz ± 20 Hz
F = 268 Hz (OR) 308 Hz
Since, 268 Hz is common from both calculations. Therefore, it will be the frequency of the tuning fork.
<u>F = 268 Hz</u>
