Answer:
The fundamental frequency is 159 Hz.
Explanation:
Given that,
First frequency = 1113 Hz
Second frequency = 1431 Hz
Third frequency = 1590 Hz
Here, three frequencies are separated from each other by the multiple of 159
We need to calculate the fundamental frequency
As,
1113 Hz is the seventh harmonic of 159.
Hence, The fundamental frequency is 159 Hz.

Answer:
the answer is C
Explanation:
i took the test just now so i am glad i can help someone in the future❣❣❣❣
<u><em>Also here is the explanation</em></u>
Note that the magnitude of acceleration (a) is given by a =
v2
R
, where v is the speed and R is the radius. Because acceleration is the same for both bikers, the ratio 
v2
R
, also has to be the same for both. Given that Kevin’s speed is higher, the radius of his path must also be higher to maintain the same ratio. Therefore, Kevin’s circular path has a bigger radius than Linda’s path.
Answer:
The rate of change of the height is - 4 ft/s
Solution:
As per the question:
Height of the person, y = 5 ft
The rate at which the person walks away,
Distance of the spotlight from the wall, x = 40 ft
Now,
To calculate the rate of change in the height, of the person when, x = 10 m:
From fig 1.
xy = 200 (1)
Differentiating the above eqn w.r.t time t:
Thus
(2)
From eqn (1):
When x = 10 ft
10y = 200
y = 20 ft
Using eqn (2):
