45 cents ___________________

23 miles ___________________

73 nautical miles SSW ___________________

2 blocks past Seabright Ave toward Capitola ____________________

A distance ____________________

A displacement ____________________

55 miles per hour ____________________

Answer 1

Scalar is a quantity which requires only magnitude not direction.

While vector is a quantity which require both magnitude and direction.

1. 45 cents: this is mere a number hence it is Scalar.

2. 23 miles: This is just the no with no direction whatsoever. This is Scalar.

3. 73 nautical miles SSW: Here direction as well as magnitude is given hence it is Vector.

4.2 blocks past Seabright Ave toward Capitola: It has both direction and magnitude hance it is Vector.

5. A distance: Distance is the magnitude like 1Km or miles. It does not have specific direction. Hence it is Scalar.

6. A displacement: It include direction e.g. 1 km to north. This is Vector.

7. 55 miles per hour: It does not contain the information about direction. Hence it is Scalar.
