Aworker leaves home at 9: 00 am, travels 40 km to the office, and then returns home at 5: 00 pm. what is the magnitude of the worker's displacement during this 8-hour span of time? 80 km 0 km 40 km 10 km/h

Hi! The answer to this problem is 0km.

Ok, the definition of displacement is the change in position.

So if in this 8 hours i first travel 40 km in one direction, and the i traveled -40km in the same direction i would be on the same place, so the total displacement would be 0 km.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

i think it would be 5
