Foraging bees often move in straight lines away from and toward their hives. suppose a bee starts at its hive and flies 680 m due east, then flies 430 m west, then 620 m east.

Represent the motion in the number line.

Movement to the east is movement to the negative side. Movement to the west is movement to the positive side.

Total displacement = -680m + 430m - 620m = -870m

Total displacement = 860m to the east.

answer is slate

hope this

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.
