Two coils have mutual inductance M = 4.15×10−4 H. The current i1 in the first coil increases at a uniform rate of 250 A/s. (a) What is the magnitude of the induced emf in the second coil? (b) Suppose that the current described is in the second coil rather than the first. What is the magnitude of the induced emf in the first coil?

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
