Which of these results from destructive interference?

1 answer:

8 0

Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.

what volume of water would be removed from an unconfined gravel aquifer 10,000 m2 in area if the water table in the aquifer drop

Alona [7]

The volume of water is 2500m³ and the fractionof the water is 73.5% of the water contained in that portion of the aquifer would have been removed.

What is aquifer?
An aquifer is a subterranean layer of porous, water-bearing rock, rock fissures, or unconsolidated materials. A water well can be used to obtain groundwater from aquifers. The features of aquifers vary widely. Aquitard is a low-permeability bed along an aquifer, while aquiclude (or aquifuge) is a solid, impermeable region below or covering an aquifer, the pressure of which could form a restricted aquifer.

Area of the unconfined aquifer=10000m².
water table drops by 1m
porosity = 34%
specific yield= 25%
Volume of water removed= Sy× volume
= 0.25×10000×1
= 2500m³

Fraction of water removed = 25/34

= 0.735
= 73.5% of water removed

A uniform solid disk and a uniform hoop are placed side by side at the top of an incline of height h. If they are released from

tigry1 [53]

Answer:

The disk will reach the bottom first.

Explanation:

As we know:

change in kinetic energy = change in potential energy

ΔK.E = -ΔP.E

$\frac{1}{2} mv^{2} + \frac{1}{2}Iw^{2} = Mgh$

$Mv^{2} +I\frac{v^{2} }{R^{2} } = 2Mgh$

$v=\sqrt{\frac{2Mgh}{M+\frac{I}{R^{2} } } }$

For the disk:

$I=\frac{MR^{2} }{2}$

For Hoop:

$I=MR^{2}$

Hence

Velocity for the disk:

$v=\sqrt{\frac{4}{3}gh }$

Velocity for the Hoop:

$v=\sqrt{gh}$

Any change in the cross section of the vocal tract shifts the individual formant frequencies, the direction of the shift dependi

Leona [35]

Answer:

The correct answer is option D.

Explanation:

It is stated in the question that constriction of the vocal tract at a place where the standing wave of a formant exhibits minimum-amplitude pressure oscillations generally causes the formant to drop in frequency so to increase formant frequency, the vocal should expand where the standing wave of a formant exhibits minimum-amplitude pressure oscillations. The answer is D.

I hope this helps.
