The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
<h3>How to calculate the
frequency of a
wave.</h3>
Mathematically, the frequency of a sound wave is given by this formula:
<u>Where:</u>
- F is the frequency of a sound wave.
- V is the velocity of a sound wave.
- is the wavelength of a sound wave.
<u>Note:</u> The frequency of the sound wave is increased four (4) times.
Substituting the given parameters into the formula, we have;
Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

Answer:
Ft = 0[N]
Explanation:
To understand this problem we must perform an analysis of forces on the X axis, which coincides with the axis of forces of dogs.
In this way performing a sum of forces on the X-axis we will have (newton's third law):
From this analysis we can see that the resulting or total force is equal to zero, since there is no movement.
The distance travelled by the baseball is 221 m.
<u>Explanation:</u>
Speed is the ratio of distance travelled to the time taken to cover any distance. So here the speed is given as 96 m/s and time is given as 2.3 seconds. Thus, we can determine the distance as product of speed with time.
Thus, distance = speed × Time
As the speed is 96 m/s and time is 2.3 seconds.
The distance = 96 × 2.3 =220.8 m
If we approximate it, the distance is 221 m. Thus, the distance travelled by the baseball is 221 m.
Answer:
The frequency of the piano string is either 1053 HZ or 1059 HZ.
Explanation:
Here we know that frequency of beats is equal to the difference between the frequencies between two waves .
Given that frequency of tuning fork is 1056 HZ .
Let the frequency of the piano be ' f ' .
Given that number of beats = 3.
We know that | 1056 - f | = 3 ;
⇒ 1056- f = ±3,
Upon solving this we get
f = 1056-3 and 1056 + 3
⇒ f = 1053 or 1059 .
Answer:
I'm pretty sure that it's -225, hope this helps
