Starting from the orgin, a person walks 4 km East during the first day and 7 km west the next day. What is the net displacement of the person from the initial point in two days

3km due West

Explanation:

Displacement is the distance traveled in a specific direction. From this definition, we can see that displacement is a vector quantity that has magnitude and direction.

So;

 For the first day, the person walks 4km East:

                                                           4km

                                     Start → first day

                                                            7km

              ←  Second day

The displacement of the boy  = 7km  - 4km  = 3km due West

the inner core.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.
