Yuki888 [10]3 years ago
3 0

Net force

  • F1-F2-F3
  • 5-10-20
  • 5-30
  • -25N

As it's negative the box will move left

Write the function y(x, t) that describes this pulse if it is traveling in the positive x-direction with a speed of 2.10 m/s. (U
Marrrta [24]

Answer:

The function is missing in the question. The function of the transverse pulse in the wire is given by $y=\frac{6}{x^2 +3}$  

Explanation:

A transverse wave can be defined as the wave whose direction of displacement is always perpendicular to the direction of propagation. For example, surface wave at water bodies. While a pulse can be defined as a sudden change in a constant quantity such as a pulse of the radiation or current.

Let the wire of infinite length in both the directions and also the magnitude of deflection of wire be in the same shape except the point of maximum deflection to move along the wire.

Thus the equation of the pulse moving the in the positive x-direction moving at the speed of 2.10 m/s is

$y=\frac{6}{(x-2.10)^2 +3}$.

Suppose that a siren makes a sound reaching 120 decibels, but a wolf’s howl only reaches 90 decibels. 120 dB is how many times l
MakcuM [25]

Answer:

I₁/I₂ = 1000

Thus, the sound of siren is 1000 times louder than the sound of wolf's howl.

Explanation:

First, we need to calculate the intensity of both the sounds. The formula for sound level is given as:

L = 10 log[I/I₀]

where,

L = Sound Level in dB

I = Intensity of sound

I₀ = Reference intensity = 10⁻¹² W/m²

<u>FOR SOUND OF SIREN:</u>

L = 120 dB

I = I₁ = ?

Therefore,

120 = 10 log[I₁/10⁻¹²]

log[I₁/10⁻¹²] = (120)/10

log[I₁/10⁻¹²] = 12

I₁/10⁻¹² = 10¹²

I₁ = (10¹²)(10⁻¹²)

I₁ = 1

<u>FOR SOUND OF WOLF'S HOWL:</u>

L = 90 dB

I = I₂ = ?

Therefore,

90 = 10 log[I₂/10⁻¹²]

log[I₂/10⁻¹²] = (90)/10

log[I₂/10⁻¹²] = 9

I₂/10⁻¹² = 10⁹

I₂ = (10⁹)(10⁻¹²)

I₂ = 10⁻³

Now, we divide the intensities:

I₁/I₂ = 1/10⁻³

I₁/I₂ = 10³

<u>I₁/I₂ = 1000</u>

<u>Thus, the sound of siren is 1000 times louder than the sound of wolf's howl.</u>

Which of the following is a correct step in the process of adding 8.0 x 10^ -2 and 6.0 x 10^ -3
dybincka [34]

Explanation:

In order to compute correctly the sum of the two terms, we have to rewrite one of them such that they have the same exponent.

The two terms are:

8.0 \cdot 10^{-2}

6.0 \cdot 10^{-3}

For instance, we can re-write the second term such as it also has a power 10^{-2}. In order to do that, we have to move the decimal point one place to the left, therefore:

6.0 \cdot 10^{-3} = 0.6\cdot 10^{-2}

At this point, the two numbers have the same exponent, so we can just add them together by adding the bases and keeping the same exponent, -2:

8.0\cdot 10^{-2} + 0.6 \cdot 10^{-2} = (8.0 + 0.6) \cdot 10^{-2} = 8.6\cdot 10^{-2}
