2. A 1.30-m long gas column that is open at one end and closed at the other end has a fundamental resonant frequency 80.0 Hz. Wh

Elina [12.6K]

To solve this problem, it will be necessary to apply the concepts related to the fundamental resonance frequency in a closed organ pipe.

This is mathematically given as

$f_n (2n+1)(\frac{v}{4L})$

For fundamental frequency n is 0, then,

$f_0 = \frac{v}{4L}$

When,

v = Velocity of sound

L = Length,

Rearranging to find the velocity,

$v = f_0 (4L)$

$v = (80Hz)(4)(1.3m)$

$v = 416m/s$

Therefore the speed of sound in this gas is 416m/s

A sled with a mass of 20 kg slides along frictionless ice at 4.5 m/s. It then crosses a rough patch of snow that exerts a fricti

uysha [10]

Answer:The sled slides 16.875m before rest.

Explanation:

$a=\frac{F}{m} =\frac{12N}{20kg}$

a=0.6 m/s²

$Vf=0=Vi-a.t$

$t=\frac{Vi}{a} =t=\frac{4.5m/s}{0.6 m/s2} =t=7.5seg$

$d= Vi.t - \frac{a.t^{2}}{2}$

$d= 4.5 * 7.5 - \frac{0.6*7.5^{2} }{2} \\\\d=16.875m$

N2 + 3H2 mc033-1.jpg 2NH3

N2+3H2->2NH3

When 3 moles of H2 react, they produce 2 moles of NH3

3 moles of H2 have a mass of 2.02 g

2 moles of NH2 have a mass of 17.0 g

So when 2.02 g H2 react, they produce 17.0 g NH3

If 26.3g H2 react with a yield of 100%, we expect…

2.02g H2_____17.0gNH3

26.3g H2_____x=221gNH3

So now let’s calculate the percentage:

221gNH3_________100%

79.0gNH3_________x=79.0*100/221=35.7%
