Question

a hummingbird can flutter its wings 4,800 times per minute.
what is the frequency of wing flutters per second?
flutters/second
what is the period for one wing flutter in seconds? round your answer to two significant figures.
seconds

Explanation:

Step1: Convert minutes to seconds

Since \(1\) minute \( = 60\) seconds.

Step2: Calculate frequency

Frequency \(f=\frac{\text{number of flutters}}{\text{time in seconds}}\). Given number of flutters per minute \(n = 4800\), time \(t=60\) seconds. So \(f=\frac{4800}{60}\).

$$

Step3: Calculate period

The formula for period \(T\) is \(T=\frac{1}{f}\). Since \(f = 80\) flutters/second, then \(T=\frac{1}{80}\).

$$
LATEXBLOCK1
$$

Answer:

Frequency: \(80\) flutters/second.
Period: \(0.013\) seconds.
