For a particular scientific experiment, it is important to be completely isolated from any magnetic field, including the earth's field. the earth's field is approximately 50 μt, but at any particular location it may be a bit more or < this. a 1.00-m-diameter current loop with 200 turns of wire is adjusted to carry a current of 0.207 a ; at this current, the coil's field at the center is exactly equal to the earth's field in magnitude but opposite in direction, so that the total field at the center of the coil is zero. what is the strength of the earth’s magnetic field at this location?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
