Answer:
* in a tube with both ends open
λ = 2L / n n = 1, 2, 3,…
* tube with one end open and the other closed.
λ = 4L / n n = (2n ’+ 1 )
Explanation:
When a sound wave enters a pipe, a resonance process occurs, whereby only some wavelengths can occur.
* in a tube with both ends open
in this case there are maximums at each end, so if the length of the had is L
λ = 2L 1st harmonic
λ = 2 L / 2 2nd harmonic
λ = 2L / 3
λ = 2L / n n = 1, 2, 3,…
* In the case of a tube with one end open and the other closed.
At the open end there is a belly and at the closed end a node
λ = 4L 1st harmonic
λ = 4L / 3 3rd harmonic
λ = 4L / 5
λ = 4L / n n = 1, 3, 5,… odd
n = (2n ’+ 1 ) where n’ are all integers

Answer:
made of metals and nonmetals is true of ionic compounds
Greater red shifts in the spectra of galaxies indicate faster speeds.
Density can be found when mass and volume is known. The density of 5 liter of water is 1000kg/m³.
<h3>What is density?</h3>
The density ρ of any substance is the ratio of mass m and its volume V.
ρ = m/V
Given is the mass of water as 5 kg and the volume is 5 liter.
as, 1 L = 10−³m³
So, 5 L = 5×10−³m³
Then, density would be
ρ = 5kg / 5×10−³m³
ρ = 1000 kg/m³
Thus, the density of 5l of water is 1000kg/m³.
