A circular loop carrying a current of 1.6 A is oriented in a magnetic field of 0.30 T. The loop has an area of 0.14 m 2 and is mounted on an axis, perpendicular to the magnetic field, which allows the loop to rotate. What is the torque on the loop when its plane is oriented at a 21° angle to the field?

The torque on the loop is Nm

Explanation:

Given:

Current A

Magnetic field T

Area of loop

Angle between magnetic field and area vector 21°

Form the formula of  torque in case of magnetic field,

 г

Where magnetic moment

 г

 г

 г Nm

Therefore, the torque on the loop is Nm

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
