SUMMARY

This discussion provides a clear method for reading a stopwatch efficiently. The small dial indicates minutes, while the big hand shows seconds. If the small hand is in a red section, users should read the red numbers for seconds; otherwise, they should refer to the black numbers. The lines on the stopwatch represent tens of seconds, facilitating quick time readings.

PREREQUISITES
  • Understanding of stopwatch components (small dial, big hand, red and black numbers)
  • Basic knowledge of time measurement
  • Familiarity with reading analog displays
  • Ability to interpret numerical values quickly
NEXT STEPS
  • Practice reading various stopwatch models to enhance speed
  • Learn about different types of timekeeping devices and their features
  • Explore techniques for improving mental math skills related to time
  • Research the history and evolution of stopwatches and timing methods
USEFUL FOR

Individuals looking to improve their time-reading skills, athletes needing precise timing, coaches, and anyone interested in mastering stopwatch usage.

You really couldn't figure this out yourself?

The small dial tells you the number of minutes. Then, if the small hand is not in a red section, you add the number of seconds by reading the black numbers, otherwise the red numbers, for the big hand. The lines then indicate the tens of seconds.

Thanks!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
