Question

scalar or vector quantity? directions: tell whether the statement below describes a vector quantity or a scalar quantity. circle the correct answer. 1.) 5 meters scalar vector 2.) 10 kilometers north scalar vector 3.) 80 kilometers per hour scalar vector 4.) 5 meters right scalar vector 5.) 26 centimeters scalar vector 6.) 1000 hectometers scalar vector 7.) 9 kilometers left scalar vector 8.) 38 kilometers right scalar vector 9.) 42 meters scalar vector 10.) 53 mm scalar vector 11.) 100 degrees celsius scalar vector 12.) 70 mph, south scalar vector 13.) 40 hertz scalar vector 14.) most water bottles are labeled 500ml, meaning they contain 500 milliliters or.5 liters of fluid. interestingly, 1ml of water at 4 degrees celsius is equal to 1 gram. we can express this quantity as 1g/ml or 1 gram per milliliter. is this quantity a... scalar or vector 15.) in the usa, myanmar (formerly burma), and liberia, the united states customary units (sometimes called imperial units) are used for measuring. some examples include 12 oz. or 12 ounces, a popular measurement for soda and 26 miles, which is roughly the distance of a running marathon. some people who run marathons choose to run a half marathon, or roughly 13.1 miles south. is this quantity a... scalar or vector

Explanation:

Step1: Recall scalar - vector definitions

A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction.

Step2: Analyze each quantity

1. 5 meters: Only magnitude, so scalar.
2. 10 Kilometers North: Has magnitude (10 kilometers) and direction (North), so vector.
3. 80 Kilometers per hour: Only magnitude of speed, so scalar.
4. 5 Meters right: Has magnitude (5 meters) and direction (right), so vector.
5. 26 centimeters: Only magnitude, so scalar.
6. 1000 hectometers: Only magnitude, so scalar.
7. 9 kilometers left: Has magnitude (9 kilometers) and direction (left), so vector.
8. 38 kilometers right: Has magnitude (38 kilometers) and direction (right), so vector.
9. 42 meters: Only magnitude, so scalar.
10. 53 mm: Only magnitude, so scalar.
11. 100 degrees Celsius: Only magnitude of temperature, so scalar.
12. 70 mph, south: Has magnitude (70 mph) and direction (south), so vector.
13. 40 hertz: Only magnitude of frequency, so scalar.
14. 1 g/ml: Only magnitude of density, so scalar.
15. 13.1 miles south: Has magnitude (13.1 miles) and direction (south), so vector.
