Wavelength and frequency have a reciprocal relationship. If one doubles, the other halves.

wave frequency and its wavelength is related by the following relation

$frequency = \frac{speed}{wavelength}$

we can also show this by

$f = \frac{v}{\lambda}$

now if speed of the wave remains constant then we can say that frequency of wave is inversely depends on the wavelength.

so we can say

<u>wavelength of wave is inversely depends on its frequency</u>

At 96Â° F the saturation density of air is 0.04 kg/m3. If the weather report says the relative humidity is 90 % when the tempera

nalin [4]

Answer:

The value is $H = 0.036 \ kg/m^3$

Explanation:

From the question we are told that

The saturation density of air is $\rho = 0.04 \ kg/m^3$

The temperature for this saturation density to occur $T_s = 96^o F$

The relative humidity at this temperature is $R_h = 90\% = 0.90$

Generally the relative humidity is mathematically represented as

$R_H = \frac{H}{\rho}$

Here H represents humidity

=> $0.90 = \frac{H}{0.04}$

=> $H = 0.90 * 0.04$

=> $H = 0.036 \ kg/m^3$

Q1) An average force of 50.0 N is exerted on a 4.0-kg cart for 2.0 seconds.

lozanna [386]

<h3>a. The impulse</h3>

The impulse is 100.0 Ns

The impulse I = Ft where

F =average force = 50.0 N and
t = time = 2.0 s

Substituting these values into the equation, we have

I = Ft

I = 50.0 N × 2.0 s

I = 100.0 Ns

The impulse is 100.0 Ns

<h3>b. Change in momentum</h3>

The change in momentum is 100 kgm/s

Since change in momentum Δp = I where I = impulse.

Since I = 100.0 Ns,

Substituting this into the equation, we have

Δp = I

= 100.0 Ns

= 100 kgm/s

The change in momentum is 100 kgm/s

<h3>c. Mass's change in velocity</h3>

The change in velocity is 25.0 m/s

Since change in momentum Δp = mΔv where

m = mass = 4.0 kg and
Δv = change in velocity.

Making Δv subject of the formula, we have

Δv = Δp/m

Substituting the values of the variables into the equation, we have

Δv = Δp/m

Δv = 100.0 kgm/s/4.0 kg

Δv = 25.0 m/s

The change in velocity is 25.0 m/s

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.
