he graph below displays the motion of an individual. The starting point is zero (0,0). Describe the motion that is occurring at EACH of the 3 line segments. (Include how they are moving in comparison to the starting point - towards, away, still and/or how their distance is changing over time)

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

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.
