Which could describe the motion of an object? check all that apply.
a)distance = 0 and displacement = 0
b)distance = 10 meters and displacement = 0
c)distance = 0 and displacement = 10 meters
d)distance = 10 meters and displacement = 10 meters
e)distance = 1 meter and displacement = 10 meters
f)distance = 10 meters and displacement = 1 meter

The correct choices are:

A)distance = 0 and displacement = 0

B)distance = 10 meters and displacement = 0

D)distance = 10 meters and displacement = 10 meters

F)distance = 10 meters and displacement = 1 meter

In fact, displacement cannot be larger than distance, because distance is the total distance travelled in any direction, while displacement takes into account the direction. When the object moves only in one direction, distance and displacement are equal; however, if the motion of the object consists of several motions into more directions (like going back and forth), the distance travelled is always larger than the displacement. For this reason, choices C) and E) are wrong.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

force tends to be low and long diustance masses are high
