Answer:

The answer is louder sounds. Resonance is the process, in which a system vibrates with increasing amplitudes, at specific frequencies of excitation. Resonance results in louder sounds. ... This is because of the surrounding environment, resonates with the cavity of the shell .

Question:

What does resonance result in?

A) Quieter sounds B) frequency, C) amplitude D) Louder sounds.

Answer:

Resonance results in louder sounds.

Explanation:

In fact, the point at which the sound show maximum amplitude is termed as resonance. Since there is an increase in amplitude, the sound turns louder, and louder. Resonance is the situation, where one body vibrates after being effected by another vibrating body. Let us take an example of two bodies ‘A’ and ‘B’ at vibration.

Let the body A is in vibration at a particular frequency. And then, let the body ‘B’ disturbs with its vibration. Now, ‘A’ imparts some additional frequency, from ‘B’, which leads to resonance. So, if the amplitude increases, the sound produced is huge, and hence louder.

tatuchka [14]

Answer:

The time period of the wave is 0.002 sec.

Explanation:

Given that,

Frequency = 0.5 kHz

Phase difference $\phi=\dfrac{\pi}{3}$

Path difference = 1.5 cm

We need to calculate the time period

Using formula of time period

The frequency is the reciprocal of time period.

$f =\dfrac{1}{T}$

$T=\dfrac{1}{f}$

Where, f = frequency

Put the value into the formula

$T=\dfrac{1}{0.5\times10^{3}}$

$T=0.002\ sec$

Hence, The time period of the wave is 0.002 sec.

Describe how does the temperature relate to density and the movement of atmospheric gases? A) As the air warms expanding its vol

cluponka [151]

The correct answer is A) As the air warms expanding its volume, decreasing its density, and the air molecules rise

The air molecules speed up and spread. If the container is closed then it may pop because the air expands. Hot air goes up and cold air goes down.

The 630 nm light from a helium neon laser irradiates a grating. The light then falls on a screen where the first bright spot is

mafiozo [28]

Answer:

The second wavelength is 482 nm.

Explanation:

Given that,

Wavelength = 630 nm

Distance from central maxim = 0.51 m

Distance from central maxim of another wavelength = 0.39 m

We need to calculate the second wavelength

Using formula of width of fringe

$\beta=\dfrac{\lambda d}{D}$

Here, d and D will be same for both wavelengths

$\lambda$ = wavelength

$\beta$ = width of fringe

The width of fringe for first wavelength

$\beta_{1}=\dfrac{\lambda_{1} d}{D}$ ....(I)

The width of fringe for second wavelength

$\beta_{2}=\dfrac{\lambda_{2} d}{D}$ ....(II)

Divided equation (I) by equation (II)

$\dfrac{\beta_{1}}{\beta_{2}}=\dfrac{\lambda_{1}}{\lambda_{2}}$

$\lambda_{2}=\dfrac{630\times10^{-9}\times0.39}{0.51}$

$\lambda_{2}=4.82\times10^{-7}$

$\lambda=482\ nm$

Hence, The second wavelength is 482 nm.

IrinaK [193]

Answer:

Apparent frequency increases for Bob and decreases for Jill.

Explanation:

Doppler effect refers to the apparent change in frequency when there is relative motion between source and the listener. When the source and listener move closer, the apparent frequency heard by the listener increases. And when the source and listener move away from each other, the apparent frequency heard by the listener decreases.

Thus, when the emergency vehicle approaches Bob, the apparent frequency of the siren increases. It moves away from Jill, the apparent frequency heard by the Jill decreases.
