The scalar x-component of a displacement vector for a trip is -70 km. Represent the trip using the x-coordinate axis. Choose Earth to be the object of reference. Use the x-axis with a positive direction pointing to the east and negative direction pointing to the west. The displacement is positive when moving in the east direction.

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

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.
