Answer:
32 km east
Explanation:
In order to find the final position of the balloon, we need to calculate its total displacement.
We have:
- Displacement towards west: 18 km
- Displacement towards east: 50 km
The two vectors are on the same line: this means that we can simply add them together (taking into account the proper direction) to obtain the total displacement.
Taking east as positive direction and west as negative direction, we have:
And since it is positive, it means that the final position of the balloon is 32 km east from its initial position.
Answer:
A physical change is an ice cube melting into water. The property is melting point. Another is a banana changing from yellow to brown and the property is color. A chemical change example is a pot or a tool rusting and turning from silver to a reddish-brown. It is also a color change, but it is different because the color changed chemically and not just by looks.

Explanation:
As Merrill watches his finger with both eyes open as he brings his finger closer to his nose, he feels his eye muscles working. This shows that her eyes Muscles have both accommodation and convergence.
Accommodation and convergence allows us to view objects both near and at far without double vision.
Since distance is a scalar and not a vector, the total distance traveled is the sum of all the distances covered throughout the journey.
In Physics, we have two categories of quantities;
The difference between vectors and scalars is that vectors has direction but scalars do not have direction. Both quantities posses magnitude.
The total distance covered can be obtained algebraically since distance is a scalar.
Hence, total distance covered = 2 cm + 6cm + 5 cm = 13 cm
