The origin of water on Earth is not yet fully understood. To test one of the hypotheses, scientists launched a gigantic observational balloon to the height of almost 130,000 feet to measure the amounts of water in comets and asteroids based on the light reflected from these objects. The science BEST SUITED to calculating the forces required to launch the balloon to the required altitude is - ANSWER Physics Which physical science is the BEST to study the composition of Earth's atmosphere? - A...
