You travel 25 meters east and then travel 48 meters south. what is your total displacement

54.1 m at (south of east)

Explanation:

Displacement is a vector connecting the initial position with the final position of motion.

In this problem, the motion consists of two parts:

- A first movement 25 m east

- A second movement 48 m south

We can therefore write a vector representing the displacement as

where i is the unit vector indicating the east direction and j the unit vector indicating the north direction.

Therefore, the total displacement is just the magnitude of this vector:

And the direction is given by

it becomes positively charged by charging it

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
