Final answer:
The question encompasses the use of physics in GPS technology and physiological sensor integration for determining precise locations, travel times, and monitoring vital signs.
Step-by-step explanation:
The question refers to the application of physics principles in technology, such as global positioning systems (GPS) and physiological sensors. GPS technology, which is present in devices like smartphones, relies on a network of satellites equipped with precise atomic clocks. The GPS function uses physics equations to calculate precise locations and travel times by analyzing the speed of light and the time it takes for signals to travel from satellites to the receiver. In Dr. Doherty's experiment, as in many other applications in medicine and navigation, understanding the physical concepts of time, distance, speed, and relative effects like time dilation is crucial. Physiological sensors, which can include heart rate monitors, pressure sensors, and acid sensors among others, are often integrated with GPS devices to provide comprehensive data in various scientific studies and practical applications, such as monitoring vital signs in extreme environments.
