Nutrient pollution. I just took the quiz and got it right
Answer:
Option D. 23.5 m
Explanation:
From the question given above, the following data were obtained:
Frequency = 200 Hz
Speed of sound in brass = 4700 m/s
Wavelength of sound in brass =?
We can obtain the wavelength of the sound in the brass by using the following formula as illustrated below:
Wave speed = wavelength × frequency
4700 = wavelength × 200
Divide both side by 200
Wavelength = 4700 / 200
Wavelength = 23.5 m
Thus, the wavelength of the sound in the brass is 23.5 m
Answer:
Explanation:
By equation of motion
Here;
S = Kutub Minar's height which is unknown
u = initial velocity = 0
a= g= 9.8 m/s2
t = time=3.84sec
By substituting the values and since u=0 then
