That is false. I just took the test and it is not the wavelength. The correct answer is antinode NOT wavelength.

A 40-cm-long tube has a 40-cm-long insert that can be pulled in and out. A vibrating tuning fork is held next to the tube. As th

Umnica [9.8K]

Answer:

The frequency of the tuning is 1.065 kHz

Explanation:

Given that,

Length of tube = 40 cm

We need to calculate the difference between each of the lengths

Using formula for length

$\Delta L=L_{2}-L_{1}$

$\Delta L=74.7-58.6$

$\Delta L=16.1\ m$

For an open-open tube,

We need to calculate the fundamental wavelength

Using formula of wavelength

$\lambda=2\Delta L$

Put the value into the formula

$\lambda=2\times16.1$

$\lambda=32.2\ cm$

We need to calculate the frequency of the tuning

Using formula of frequency

$f=\dfrac{v}{\lambda}$

Put the value into the formula

$f=\dfrac{343}{32.2\times10^{-2}}$

$f=1065.2\ Hz$

$f=1.065\ kHz$

Hence, The frequency of the tuning is 1.065 kHz

Two electromagnets contain the same types of magnets

Ira Lisetskai [31]

Answer: The first electromagnet has a more powerful current than

the second

Explanation:

Since the two electromagnets contain the same types of magnets and wires. If the magnet In the first moves much faster than the second. Therefore:

The first electromagnet has a more powerful current than the second

Because the induced EMF is proportional to the induced current.

Where the induced EMF depends on the speed of the magnet according to the formula below

EMF = BVL

So, increase in speed of the magnet will cause more powerful induced current and emf
