Question
**Problem 1: Heart Rate Calculations** 1. Suppose that a person has an average heart rate of 72.0 beats/min. Assume that a year has 365 days. Note the significant figures in each question. **Note:** When entering the answer in the box, use the asterisk symbol (*) for multiplication or the multiplication symbol in the math editor (orange box). (a) How many beats does he or she have in 2.0 years? - Answer Input: 7.5 * 10^7 (incorrect) (b) In 2.00 years? - Answer Input: [Blank] (c) In 2.000 years? - Answer Input: [Blank] --- **Think & Prepare** 1. How many significant digits are there in the number of heartbeats? 2. How many significant digits are there in the number of years? 3. Which quantity is less precise? 4. When you multiply both quantities, what will be the precision of the product? --- **Feedback Section** - Message: No, that's not the correct answer. --- The section encourages learners to think about significant figures and precision in calculations involving unit conversions and multiplication, with focus on understanding rounding and scientific notation to ensure accurate results.
