I think the answer would be Equal Responsibility as the paragraph did not mention Antonia presenting their work with Jan and Finn.

Two loudspeakers, A and B are driven by the same amplifier

DedPeter [7]

<h3><u>Complete Question </u></h3>

Q)Two loudspeakers, A and B, are driven by the same amplifier as shown and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speakers emit sound waves that travel directly from the speaker to point Q. a) What is the lowest frequency for which constructive interference occurs at point Q? b) What is the lowest frequency for which destructive interference occurs at point Q? The speed of sound wave is 344 m/s.

Answer:

lowest frequency is 172 Hz. for n = 1

lowest frequency is 86 Hz for n = 0

Explanation:

(a) Constructive interference takes place when the path difference is n where n=1,2,3 ...

frequency f = v /λn

= v n / d

= n ( 344 / 2 )

= n ( 172 ) Hz.

lowest frequency is 172 Hz

b)Destructive interference takes place when the path difference is n/2 x where n=1,3,5 ...

λ = 4/2n+1

for n = 0

λ = 4m

f = 344/4

f = 86 Hz.

lowest frequency is 86 Hz

Suppose you charges parallel plate capacitor with a dielectric between the plates using a battery and the. Remove the bater, iso

Makovka662 [10]

Answer:

A) increase.

Explanation:

By definition, the capacitance of a capacitor, is the charge on one of the plates, divided by the potential difference between them, as follows:

$C = \frac{Q}{V} (1)$

At the same time, we can show (applying Gauss' Law to the surface of one of the plates), that the capacitance of a parallel-plate capacitor (with a dielectric of air), can be written as follows:

C = ε₀*A / d (2)

If the space between plates, is filled with a dielectric of dielectric constant κ, the above equation becomes:

$C =\frac{\epsilon_{0}*\kappa*A}{d} (3)$

If the capacitor, once charged, is disconnected from the battery, charge must keep the same.
Now, if we remove the dielectric, as stated in (3) and (2), the capacitance C will decrease when removing the dielectric.
From (1) if C decreases, and Q remains constant, in order to keep both sides of the equation equal each other, V (the potential difference between plates), must increase.
