An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.19 m apart are powered by the same function generator producing sine waves at 1,163 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m

Answers

Answer:

3.04 m

Explanation:

The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.

It is given that :

Distance between two speakers, d = 1.19 m

Speed of sound,  v = 340 m/s

The frequency is f = 1163 Hz

Distance the student walk along the line of the speaker, D = 12.5 m

We know the wavelength of the sound produced by the speakers is given by :

[tex]$\lambda=\frac{v}{f}$[/tex]

  [tex]$=\frac{340}{1163}$[/tex]

  = 0.29 m

Now the distance between the central maximum and the first maximum position is given by :

[tex]$y=\frac{\lambda D}{d}$[/tex]

  [tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]

 = 3.04 m

Resolver: Una bala de 0.8 de masa se mueve horizontalmente con una velocidad de 30 m/s y se introduce en un bloque de 4kg, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Answers

Answer:

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:

Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:

[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)

Donde:

[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.

[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.

[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.

[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.

Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:

[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]

[tex]v = 5\,\frac{m}{s}[/tex]

La velocidad del sistema bala-bloque es 5 metros por segundo.

Australian Tiger beetles can travel 2.5 m/s. How long would it take a tiger beetle to run the length of a standard football field (109.7 m)?

Answers

Answer:

Time = 43.88 seconds

Explanation:

Given the following data;

Speed = 2.5 m/s

Distance = 109.7 m

To find the time it would take to run the length of a standard football field, we would use the following formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making time the subject of formula, we have;

[tex]Time = \frac{distance}{speed}[/tex]

Substituting into the formula, we have;

[tex]Time = \frac{109.7}{2.5}[/tex]

Time = 43.88 seconds

Therefore, it would take a tiger beetle 43.88 seconds to run the length of a standard football.

$

,
600
$20,600?

Answers

Answer:

8.5

Explanation:

To the nearest tenth of a year, it would take around 9.1 years when calculate compoundly for the account's worth to reach $20,600.

What is Compound interest?

A loan or investment's initial principal as well as any accrued interest from earlier periods are both taken into account when calculating compound interest.

To resolve this issue, we can apply the compound interest formula:

A = P(1 + r/n)nt

where:

A represents the balance of the account after t years.P stands for the initial outlay ($8,900 in this case).The annual interest rate is r, which is unknown.The number n determines how often interest is compounded each year (in this case, once every seven years because the value of the money doubles every seven years).The number of years is t.

When A = $20,600, we need to determine t. Since we are aware that the initial investment would double after seven years, we can use the following formula to determine the yearly interest rate:

2 = (1 + r/n)^(nt)

If n is 1/7 (since the investment twice once every 7 years), 2 is the factor by which the investment doubles, and t is an unknown.

When we simplify this equation, we obtain:

t log(1 + r/7) = log(2)

When we solve for r, we get:

r = 7[(2^(1/t))-1]

Now that we have P, r, n, and A, we can enter them into the compound interest formula to find t:

$20,600 = $8,900(1 + r/1)^(1t)

2.318 = (1 + r)^t = log (2.318) / log (one plus r)

t is equal to log(2.318)/log(1 + 7[(2(1/t))-1]).

We can iteratively solve for t using a calculator, beginning with a first guess of 7 years (because the investment doubles every 7 years):

r = 0.0998 and A = $17,800 for t = 7 years

r = 0.0909 and A = $19,397 for t = 8 years.

r = 0.0833 and A = $20,416 for t = 9 years.

r = 0.0823 and A = $20,601 (closest to $20,600) for t = 9.1 years

As a result, it would take the account's value to reach $20,600 in around 9.1 years (to the nearest tenth of a year).

Therefore, when calculated compoundly, it would take approximately 9.1 years for the account's value to reach $20,600, to the nearest tenth of a year.

A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?

Answers

Use the formula f=kx where f is force, k is spring constant, and x is extension.

1500=k* 0.15
K= 1500/0.15 = 10000

The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.

What is spring constant?

The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.

The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.

If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.

We know that,

F = k(x)

Where k is the spring constant.

Here, it is given that:

F = 1500N

x = 0.15m

So,

1500 = k (0.15)

k (0.15) = 1500

k = 1500/0.15

k = 150000/15

k = 10000

Thus, the value of spring constant is 10000.

2. A₂ = 1.2 A

Explanation:

1. Determination of the voltage measured at R₃.

Voltage at R₁ (V₁) = 1 V

Voltage at R₂ (V₂) = 6 V

Total voltage (Vₜ) = 12 V

Voltage at R₃ (V₃) =.?

Vₜ = V₁ + V₂ + V₃

12 = 1 + 6 + V₃

12 = 7 + V₃

Collect like terms

12 – 7 = V₃

V₃ = 5 V

Thus, the voltage measured at R₃ is 5 V

2. Determination of A₂.

From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.

Thus,

A₂ = A₁ = 1.2 A

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

One type of slingshot can be made from a length of rope and a leather pocket for holding the stone. The stone can be thrown by whirling it rapidly in a horizontal circle and releasing it at the right moment. Such a slingshot is used to throw a stone from the edge of a cliff, the point of release being 25.6 m above the base of the cliff. The stone lands on the ground below the cliff at a point X. The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle on which the stone is whirled. Determine the angular speed of the stone at the moment of release

Answers

Answer:

the angular speed of the stone at the moment of release is 15.05 rad/s

Explanation:

Given the data in the question;

The point of release ( height ) h = 25.6 m

the time of the fall of the stone will be;

⇒√( 2h/g )

we know that g = 9.81 m/s

so we substitute

t = √( (2 × 25.6 m) / 9.81 m/s )

t = √( 51.2 / 9.81 m/s )

t = √( 5.219164 s )

t = 2.285 s

Now, let v represent velocity at the time of release

them v × t ~ v × 2.285 s is the horizontal distance traveled.

Given that; The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle.

so

v × 2.285 = 34.4 × radius

Now, if the angular speed is ω then velocity at the time of release will be;

v = radius × ω

hence;

(radius × ω)  × 2.285 = 34.4 × radius

radius cancels each other out and we have;

ω  × 2.285 = 34.4

ω = 34.4 / 2.285

ω = 15.05 rad/s

Therefore, the angular speed of the stone at the moment of release is 15.05 rad/s
