Answer:
The length of the open closed pipe is 12.25 cm
Explanation:
In open - open organ pipe, third harmonic has Antinode to Node, Node to Node, Node to Node and Node to Antinode.
The length of the open-open organ pipe is equal to the sum of wavelength in Antinode to Node, Node to Node, Node to Node and Node to Antinode.
L = A→N + N→N + N→N + N→A
In open-closed pipe, Fundamental frequency has Antinode to Node.
Thus, length of the open-closed organ pipe is equal to the wavelength in Antinode to Node.
L = A→N
From the information in the question, fundamental frequency of open-closed pipe is to the third harmonic of the open-open pipe.
F₀ = F
Therefore, the length of the open closed pipe is 12.25 cm
Answer:
40.7 m
Explanation:
Let point 1 represent the surface of the water, point 2 be the top of the water trajectory and the reference be the bottom of the tank. Hence:
Answer:
t=5.5 mm
Heat dissipation per unit length = 90.477 W/m
Explanation:
Given that
Diameter d = 5 mm ⇒r = 2.5 mm
Conductivity of insulated material K = 0.16 W/mK
Heat transfer coefficient = 20
When thickness reaches up to critical radius of insulation then heat dissipation will be maximum
We know that critical radius of insulation of wire is given as follow
Now by putting the values
So the thickness of insulation
t=8-2.5 mm
t=5.5 mm
As we know that heat transfer due to convection given as follows
Q = hAΔ T
Q=20 x 2 x π x 0.008 x (120-30)
Q = 90.477 W/m
So heat dissipation per unit length = 90.477 W/m
Answer:
afternoon in winter
Explanation:
because sun have little slanting that time
