An effective treatment for some cancerous tumors involves irradiation with fast neutrons. The neutrons from one treatment source have an average velocity of 5.7 x 10 m/s. If the velocities of individual neutrons are known to within 2% of this value, what is the
uncertainty in the position of one of them?

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
