What is the equation for an open system?

Select the correct answer(s).

(0/0)

Explanation

THe conservation of Mass: Mass within an isolated system will remain constant (A + B = Constant) , the hydrological cycle is not a closed system!

Why do we use tipping buckets?

Select the correct answer(s).

(0/0)

Explanation

Tipping buckets are used because they're cheaper and smaller, we can place them over several locations to get an average using the pythagoras theorum.
