Avery thin circular disk is on the xy-plane and carries a uniform magnetization that points in the positive z-axis. calculate the magnetic field at the center of the surface of the disk.

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Ibelieve the answer is b

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )
