An organ pipe open at both ends has a radius of 4.0 cm and a length of 6.0 m. what is the frequency (in hz) of the third harmoni
Marysya12 [62]

When air is blown into the open pipe,

L = \frac{nλ}{2}

where nis any integral number 1,2,3,4 etc. and λ is the wavelength of the oscillation

⇒λ=\frac{2L} {n}

Note here that n=1 is for fundamental, n=2 is first harmonic and so on..

⇒ third harmonic will be n=4

Given L=6m, n=4, solving for λ we get:

λ=\frac{(2)*(6)}{4} =3m

Relationship of frequency(f), velocity of sound (c) and wavelength(λ) is:

c=f.λ Or f= \frac{c}{λ}

⇒f=\frac{344}{3}

≈115 Hz

A hockey puck sliding at 60.0m/s slows uniformly to 20.0m/s while travelling 800.0m.
julia-pushkina [17]
A) -3.75 meters/second
A=(20^2-80^2)/(2x800)
=(400-6400)/1600
=-6000/1600
=-3.75
B) 16 seconds
t=(20-80)/-3.75
=-60/-3.75
=16

Which of the following summarizes cellular respiration?
3241004551 [841]

The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

<h3>What is cellular respiration?</h3>

Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.

The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.

The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces  carbon- di- oxide and water along with the release of energy.

Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.
