Answer:
The Astronomical Unit (AU) is approximately , the ratio of Astronomical Units per mile is .
Explanation:
The distance from the Earth to the Sun is approximately , then the Astronomical Unit (AU) is approximately . The ratio can be described by the quantity of miles per Astronomical Unit, then we define:
.
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>
