(a) What resonant frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep, if you assu
Kryger [21]

Answer:

a) 357.29 Hz

b) 535.9375 Hz

Step-by-step explanation:

v = Velocity of sound in air = 343 m/s

l = length = 24 cm

a)

l=\frac{1}{4}\lambda \\\Rightarrow \lambda=4l

f=\frac{v}{\lambda}\\\Rightarrow f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.24}\\\Rightarrow f=357.29\ Hz

∴ Resonant frequency is 357.29 Hz

b) Here one third is filled with soda

So, length becomes l=24-\frac{24}{3}=16\ cm

f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.16}\\\Rightarrow f=535.9375\ Hz

∴ Resonant frequency is 535.9375 Hz

Nataly [62]

Answer:

ab • (11a + b + 1)  If its not im really sorry

Step-by-step explanation:

STEP one

 (((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)

STEP Two

 ((((3a2 • b) +  5ab) -  4ab) +  ab2) +  23a2b

STEP 3

STEP 4

Pulling out like terms

4.1     Pull out like factors :

  11a2b + ab2 + ab  =   ab • (11a + b + 1)

Find the distance between (2,3) and (5,8)
Orlov [11]
Use pythagorean theorem
a^2+b^2=c^2

first find the difference of between the 2 points to find the legnth of the legs

distance between 2 and 5=3
distance between 3 and 8=5 so


3^2+5^2=c^2
9+25=c^2
34=c^2
√34=c

the ligit formula is
c= \sqrt{(x1-x2)^2+(y1-y2)^2}
