Why is a rotated coordinate system used to solve an inclined plane problem? A) Reduce the number of forces that need to be resolved into their x and y components.
B) To eliminate the need to consider the force of gravity.
C) To align the coordinate axes with the acceleration of the object on the plane.
D) To minimize the number of forces that need to be considered.

Actually the answer is C, To align the coordinate axes with the acceleration of the object on the plane.

c) power lifting, will be your answer.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
