Question

which description depicts a periodic scenario? (1 point)

○ the height of an elevator in an office building

○ the temperature of an ice cube taken out of the freezer

○ the distance of a metronome from center as it keeps time

○ the amount of air in a tire

Explanation:

To determine a periodic scenario, we identify a process that repeats at regular intervals.

• The elevator's height changes non - periodically (stops at floors).
• An ice cube's temperature rises until it reaches room temp (non - periodic).
• A metronome's distance from center oscillates regularly (periodic motion).
• Air in a tire is constant (non - periodic).

Answer:

the distance of a metronome from center as it keeps time
