Understanding Cyclical Patterns in Ferris Wheel and Heart Activity

The video tutorial discusses two problems: one involving Divya's height on a Ferris wheel over time, and another about Finn's heart electrical activity. It explains how to determine the time for one full revolution of the Ferris wheel and how to analyze graphs to identify the correct representation of heart activity based on peak intervals.

What is Divya's initial height from the ground when the ride starts?

• 2.5 meters

• 1 meter

• 1.5 meters

• 2 meters

How high does Divya reach at the peak of the Ferris wheel?

• 30 meters

• 34 meters

• 36 meters

• 32 meters

How long does it take Divya to complete one full revolution on the Ferris wheel?

• 45 seconds

• 30 seconds

• 60 seconds

• 90 seconds

What is the nature of Finn's heart activity as observed by the doctor?

• Cyclical

• Random

• Linear

• Constant

At what interval does Finn's heart activity peak?

• 0.5 seconds

• 1.1 seconds

• 0.7 seconds

• 0.9 seconds

Which graph characteristic is NOT suitable for representing Finn's heart activity?

• Peaks every 0.75 seconds

• Peaks every 1.1 seconds

• Peaks every 0.9 seconds

• Peaks every 0.5 seconds

Which graph option was identified as the best representation of Finn's heart activity?

• Option A

• Option B

• Option C

• Option D

How many peaks should be observed in 3.6 seconds if the heart activity peaks every 0.9 seconds?

• 2 peaks

• 3 peaks

• 4 peaks

• 5 peaks

What is the total time taken for four peaks if the heart activity peaks every 0.9 seconds?

• 3.6 seconds

• 2.7 seconds

• 5.4 seconds

• 4.5 seconds

What method can be used to verify the accuracy of the graph representation?

• All of the above

• Eyeballing the graph

• Counting the number of peaks

• Checking the time interval between peaks
