Amagnetic field of magnitude 1.30x10-3 t is measured a distance of 0.03 m from a long straight wire. what is the current through the wire?

Explanation:

According to the Biot–Savart law, the magnitude of a magnetic field created by the current in a long straight wire, is defined as:

Where is the permeability of free space, I is the current circulating on the wire and R is the distance from the point where B is measured.

Solving for I:

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
