Homework Answers
Scalar quantities are those quantities that only need magnitude(and not direction) for their complete description. These quantities follow normal rules of scalar algebra.
Option a is correct because mass , speed and volume, all of them are scalar quantities as they need only magnitudes for their complete description.

6. A 50.0 kg man standing on a spring scale takes a descending elevator ride (DOWNWARD). Starting from the rest, the elevator descends, attaining a maximum speed of 6.0 m/s in 2.0 seconds. Then the elevator travels with this constant speed of 6.0 m/s for 10.0 seconds. Lastly, it takes the elevator 3.0 second to make a complete stop. Based on the information above, answer the...
