You know that the frequency and wavelength of an oscillation are related by the velocity of the wave (Eq. 1). In standing waves, the wave velocities of the different harmonics are the same. Think about why this may be and explain in your notebook. (Hint: The wave velocity is dependent on the static properties of the oscillating object like string mass and tension)

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
