(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

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

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

∴ 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

A bus gets off the freeway, stops at a rest stop for passengers to get lunch, and then gets back on the freeway.

lozanna [386]

I believe the first graph in the shape of the \_/ is the correct graph because when he gets off the freeway his speed slows then he stops and is no longer moving for a period of time. Then he gets back on and his speed is going up.

Mr Wellborn arrives at work at 7:50 am. If you take 60 minutes away from 8:40 its 7:40 but take away 10 minutes and its 7:50.

Answer:

1 ) 49,062.5 feet square

2) 64 π inch square .

3) 9 π meter square .

4) 289 π ft square.

5) 225 π cm square .

Step-by-step explanation:

1) From the above figure we can see that diameter of pond is given as 250 ft.

So we easily calculate the area of circular pond by using the area formula of circle.

AREA $= \frac{\pi }{4} * diameter^{2}$

= 0.785 × 250 × 250 ft square

= 49,062.5 ft square .

2) In the second figure diameter is given as 16 inches .

AREA $= \frac{\pi }{4} * diameter^{2}$

= $\frac{\pi }{4} * 16^{2}$

= 64 π inch square .

3) Here the diameter is given as 6 m .

AREA $= \frac{\pi }{4} * diameter^{2}$

= 9 π meter square .

4) Here the radius is 17 ft .

AREA = π × radius ×radius

= π × 17 × 17 ft. square .

= 289 π ft square.

5) Here the radius is give as 15 cm.

AREA = π × radius ×radius .

= π × 15 × 15 cm square .

= 225 π cm square .
