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 - Physics Which physical science is the BEST to study the composition of Earth's atmosphere? - Earth Science The science BEST for studying how hydrogen sulfide and carbon dioxide react is - Chemistry The science BEST for studying photosynthetic bacteria is - Life Science What is usually the main advantage of being able to do a laboratory experiment rather than a field study if both investigations allow you to collect similar information? - It is possible to change only one variable at a time. Some students carry out an experiment in which they tilt a wooden plank by propping up one end with books, so that its height is a distance h above the table. The students release a steel ball
