Answer:
258 Hz or 266 Hz
Explanation:
When two sounds of similar frequency occur at the same time, a phenomenon called "beat" occurs. The beat is an interference patter between the two sounds; the frequency of this beats (called beat frequency) is given by the difference between the frequencies of the two sounds:
where
is the beat frequency
is the frequency of the 1st sound
is the frequency of the 2nd sound
In this problem,
is the beat frequency
is the frequency of the middle C tuning fork
is the frequency of the middle C piano string
Solving for f2, we find two solutions:
Answer:
The maximum volume is 1417.87
Explanation:
<u>Optimization Using Derivatives</u>
We have a 24x30 inch piece of metal and we need to make a rectangular box by cutting a square from each corner of the piece and bending up the sides. The width of the piece is 24 inches and its length is 30 inches
When we cut a square of each corner of side x, the base of the box (after bending up the sides) will be (24-2x) and (30-2x), width and length respectively. The volume of the box is
Operating
To find the maximum value of V, we compute the first derivative and equate it to zero
Simplifying by 12
Completing squares
We have two values for x
The first value is not feasible because it will produce a negative width (24-2(13.58))=-6.16
We'll keep only the solution
The width is
The length is
And the height
The maximum volume is
Magnitude: Magnitude generally refers to the quantity or distance.
Attraction: A force that makes things move together and stay together.
Repulsive: The feeling of being repelled, as by the thought or presence of something; distaste, repugnance, or aversion.
Current: Current is the rate of flow of electric charge. A potential difference (voltage) across an electrical component is needed to make a current flow through it.
I hope that helps :]
