Answer:
The minimum difference between the lengths of the two tubes should be 0.385 meters.
Explanation:
As we known that for any two waves to arrive in phase at any point the difference in the path traveled by the waves should be an integral multiple of the wavelength of the wave.
Mathematically we can write:
For the given wave we have
Applying values we get
Thus the minimum difference in the lengths of the tubes can be obtained by putting the value of n = 1
Answer:
Earth Rotation
Explanation:
Earth Rotation seems like the answer
Answer:
F = 1.68 N
Explanation:
Let's solve this exercise in parts.
Let's use the concept of conservation of the mechanical nerve
initial
Em₀ = 500 J
The energy is totally kinetic
Em₀ = K = ½ m v₀²
v₀ =
v₀ = √ (2 500/32)
v₀ = 5.59 m / s
now with kinematics we can find a space
v² = v₀² - 2 a x
the negative sign is because the body is stopping
a =
let's calculate
a = (5.59² - 5.1²) / 2 50
a = 0.0524 m / s²
Finally let's use Newton's second law
F = ma
F = 32 0.0524
F = 1.68 N
An antinode must occur at B, the open end of the pipe
Explanation:
For the standing waves produced in a pipe, open and closed ends reflect waves in a different way, so their behaviour is different. In particular:
- A closed end acts as a node (because there is no vibration of the wave)
- An open end acts as an antinode (maximum vibration of the wave)
This means that for the pipe in this problem:
A (the closed end on the right) must act as a node of the standing wave
B (the open end on the left) must act as an antinode of the standing wave
Therefore the correct answer in this problem is that an antinode must occur
at B, the open end of the pipe
