i

Lenz's law states that the direction of the current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field which produced it. Lenz's Law is named after the German scientist H. F. E. Lenz in 1834

ii Faraday's experiment : Induction from a magnet moving through a coil. The key experiment which lead Michael Faraday to determine Faraday's law was quite simple. ... A voltmeter was connected across the coil and the induced EMF read as a magnet was passed through the 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
