13. A man moves $4 \, \text{km}$ southward, then $4 \, \text{km}$ westward and finally $4 \, \text{km}$ northward. The displacement of the man is:
Step 1: Analyze the movements in components.
• Southward movement: $4 \, \text{km}$ (let's consider South as negative y-direction)
• Westward movement: $4 \, \text{km}$ (let's consider West as negative x-direction)
• Northward movement: $4 \, \text{km}$ (let's consider North as positive y-direction)
Step 2: Calculate the net displacement in each direction.
• Net displacement in the North
