Asound wave with a frequency of 300 hertz is traveling through a medium at a speed of 320 meters/second. what is its wavelength?

Wavelength is 1.06 meters

Explanation:

Given that,

The frequency of sound wave, f = 300 Hz

Speed of sound wave, v = 320 m/s

We need to find the wavelength of this wave. The formula is given by :

So, the wavelength of the wave is 1.06 meters. Hence, this is the required solution.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
