A sound wave, generated at a frequency of 440 hertz has a wavelength of 2.3 meters as it travels through a solid material. The a
Jlenok [28]

The approximate speed of the sound wave traveling through the solid material is 1012m/s.

<h3>Wavelength, Frequency and Speed</h3>

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

  • Frequency of sound wave f = 440Hz = 440s⁻¹
  • Wavelength of the wave λ = 2.3m
  • Speed of the wave v = ?

To determine the approximate speed of the wave, we substitute our given values into the expression above.

λ = v ÷ f

2.3m = v ÷ 440s⁻¹

v = 2.3m × 440s⁻¹

v = 1012ms⁻¹

v = 1012m/s

Therefore, the approximate speed of the sound wave traveling through the solid material is 1012m/s.

As water rises through the troposphere and cools, it changes from a(n) ————- to a(n) ———— through the process of condensation; w
Hoochie [10]

Answer:

GAS,   LIQUID,    CLOUDS

Explanation:

Water can be in three states: solid, liquid and gas, passing from one to another depending on the pressure and temperature.

In this complementation exercise.

When the water cools down the GAS goes to the LIQUID state, these small drops unite and form the CLOUDS

Tests reveal that a normal driver takes about 0.75 s before he or she can react to a situation to avoid a collision. It takes ab
nata0808 [166]

To solve this problem we will apply the linear motion kinematic equations. On these equations we will define the speed as the distance traveled in a space of time, and that speed will be in charge of indicating the reaction rate of the individual. In turn, using the ratio of speed, position and acceleration, we will clear the position and determine the distance necessary for braking.

The relation to express the velocity in terms of position for constant acceleration is as follows

v^2 = u^2+2a(s-s_0)

Here,

u = Initial velocity

v= Final velocity

a = Acceleration

s_0 = Initial position

s = Final position

PART 1) Calculate the displacement within the reaction time

d = vt

d = (44)(0.75)

d = 33ft

In this case we can calculate the shortest stopping distance

0^2 = 44^2+2(-2)(s-33)

s = 517ft

PART 2)

PART 1) Calculate the displacement within the reaction time

d = vt

d = (44)(3)

d = 132ft

In this case we can calculate the shortest stopping distance

0^2 = 44^2+2(-2)(s-132)

s = 616ft

While a person without alcohol would cost 517ft to slow down, under alcoholic substances that distance would be 616ft
