If the organ pipe is cut in half, what is the new fundamental frequency? if the organ pipe is cut in half, what is the new fundamental frequency? 4f0 2f0 f0 f0/2 f0/4

The frequency for a fundamental pipe is given as:

f = v/4L

L is equal to the length of the pipe

Since L = Lo/2 where Lo is the original length of the pipe, the new frequency would be:

f = (v/4)/(Lo/2)

f = 2 (v/4Lo)

Since v/4Lo = fo, therefore:

f = 2 fo

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

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
