What happens to the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere?

2 answers:

7 0

Constructive interference means that the waves combine instead of negate. if they are both amplitude x, adding them together would result in 2x, or doubling the amplitude of one of the waves

Answer:

The amplitude of the resultant wave will be twice the amplitude of each wave

Explanation:

- Constructive interference occurs when two waves meet in phase ( $\theta=0^{\circ}$ , which means that the crest of a wave meets the crest of the other wave: in this case, the amplitude of the resultant wave is the sum of the amplitudes of the single waves

- Destructive interference occurs when the two waves meet in anti-phase ( $\theta=180^{\circ}$ , which means that the crest of a wave meets the trough of the other wave: in this case, the amplitude of the resultant wave is the difference between the amplitudes of the single wave

In this problem, we have constructive interference between the two waves: this means that the resultant amplitude is the sum of the two waves. Since the two waves have equal amplitude (we can call it A), the resultant amplitude will be

$R= A+A=2 A$

so, twice the amplitude of the single wave.

tatyana61 [14]

Answer:

0.76

Explanation:

we are given:

radius (r) =5.7 m

speed (s) = 1 revolution in 5.5 seconds

acceleration due to gravity (g) = 9.8 m/s^{2}

coefficient of friction (Uk) = ?

we can get the minimum coefficient of friction from the equation below

centrifugal force = frictional force

m x r x ω^{2} = Uk x m x g

r x ω^{2} = Uk x g

Uk = $\frac{ r x ω^{2} }{g}$

where ω (angular velocity) = $\frac{2π}{time}$

= $\frac{2π }{5.5}$ = 1.14

Uk = $\frac{ 5.7 x 1.14^{2} }{9.8}$ = 0.76

Calculate the net force on particle q1. First, find the direction of the force particle q2 is exerting on particle q1. Is it pus

ValentinkaMS [17]

The net force on particle particle q1 is 13.06 N towards the left.

<h3>Force on q1 due to q2</h3>

F(12) = kq₁q₂/r₂

F(12) = (9 x 10⁹ x 13 x 10⁻⁶ x 7.7 x 10⁻⁶)/(0.25²)

F(12) = -14.41 N (towards left)

<h3>Force on q1 due to q3</h3>

F(13) = (9 x 10⁹ x 7.7 x 10⁻⁶ x 5.9 x 10⁻⁶)/(0.55²)

F(13) = 1.352 N (towards right)

<h3>Net force on q1</h3>

F(net) = 1.352 N - 14.41 N

F(net) = -13.06 N

Thus, the net force on particle particle q1 is 13.06 N towards the left.

What is the mechanical advantage of the wheel and axle shown below?

BigorU [14]

The correct answer is A. 32.5

Mechanical advantage is the ratio of force that is input into a machine to the force output.

Mechanical advantage of a wheel and axle is calculated by dividing the radius of the wheel by that of the axle.

MA=R/r where R is the radius of the wheel and r is the radius of the axle.

Substituting for the values in the question gives:

MA=26cm/0.8cm

=32.5

The ______ clause in an if statement allows a program to make one choice if the condition is true, and anothere choice if the co

Inessa [10]

Answer: The IF clause.

Explanation: This is the IF clause; you can use it as:

IF (something = true) then "something happens"

else "other thing happens"

Some example of it can be, suppose that your program reads a number X that the user inputs, then you can do:

If ( X > 5) then

print: "the number X is bigger than five"

Else

print: "the number X is smaller than five"

Where, of course, the statements depend on the language used, but the "if" clause works almost the same in every language.
