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
The answer is hardness and brittleness. The ion discharging procedure and taking after impact on reservoir water quality file, for example, hardness, pH, conductivity, has been dissected. Comes about uncovered that the most discharge quality of various materials was touching base at the 30s after startup.
Answer:
Its a ceramic
Explanation:
Brick does not contain any metal so it couldnt be an alloy.
Visible light waves are the type of electromagnetic waves that make up the colors of the rainbow, because the rainbow is visible to us.
Answer:
Explanation:
From free falling objects we know that height is equal to:
From the exercise we know that
Being said that, we can calculate how long would it take to the object to hit the ground knowing that the height at that point is 0
Solving the quadratic formula we got that
or
Since time can not be negative the logical answer is <u><em>t=5s</em></u>
So, the object hit the ground at 5s
