Question

Snow is piling outside Cameron's house. He decides to measure the rate at which the height of the pile increases over time.

What would be an appropriate unit for Cameron's purpose?

A.) minutes per liter
B.) hours per meter
C.) meters per hour
D.) liters per minute

Answer 1

D.) liters per minute

Explanation:

When measuring S. I units, the major things considered are whether the units are vector (magnitude and direction) or scalar quantity (magnitude only).

Why the answer is D is because if you consider the units in the other options, you quickly discover that they are not an accurate description of the above scenario.

Meter per hour has to do with acceleration, which is a vector quantity as its the rate of change of speed over time. It has nothing to do with the gathering of snow over time.

The correct answer is D litres per minute because it has to do with the cube length over time.
