The frequency of the wave is 67 $s^{-1}$ or Hz , if a wave travels at 335 m/s and the distance from one crest to the following crest is other is 5 m.

Step-by-step explanation:

The given is,

Wave travels at 335 m/s

Distance from from crest to the following crest is 5m

Step:1

Formula to calculate the Frequency of wave is,

$Frequency, f= \frac{Velocity}{Wavelength}$ ..............................(1)

From given values,

Velocity = 335 m/s

Wavelength = 5 m

( wavelength - The distance from one crest to the following crest)

From the equation (1),

$f = \frac{335}{5}$

= 67 ( $f = \frac{m}{(s)(m)} = \frac{1}{s} = s^{-1}$ )

frequency, f = 67 $s^{-1}$

(∵ $s^{-1} = Hz$ )

Frequency, f = 67 Hz

Result:

The frequency of the wave is 67 $s^{-1}$ or Hz , if a wave travels at 335 m/s and the distance from one crest to the following crest is other is 5 m.

Answer from: Quest

$7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m$

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

$1 nm = 10^{-9} m\\1 mm = 10^{-3} m$

let's start from the lower value, we have:

$700 nm = 700 \cdot 10^{-9} m = 7.00 \cdot 10^{-7} m$ (we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

$1 mm = 1 \cdot 10^{-3} m$

so, the range of wavelength of infrared radiation is:

$7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m$

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
