A200 turn circular loop of radius 65 cm is lying flat on the ground with a current of 85 a circulating counterclockwise (when viewed from above) in a location where the earth’s field is pointed north, but at an angle 45.0° below the horizontal and with a strength of 6.15 × 10-5 t . what is the magnitude of the torque on the loop, in n⋅m?

torque on the loop is 0.9812 Nm

Explanation:

given,

circular loop of 200 turns

radius = 65 cm

current in the loop = 85 A

Earth field is pointed north, but at an angle 45.0°

B = 6.15 × 10⁻⁵ T

torque on the loop = ?

using formula

hence, torque on the loop is 0.9812 Nm

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
