AP:hydroponics
Determine the maximum number of plants that can be supported in a hydroponics system. Given the parameters from class.
Density of foam- 100kg/m^3
Mass of plants-.5kg
Volume of foam- .012m^3
Radius of opening in foam for plant r- .08m
Key to solution.
Draw a picture
Create a fbd
Write an equation For sum of forces interms of the number of plants
Set sum = 0
Solve for # of plants
You should include at minimum the step listed above. A nice picture with some color would be awesome.
Oh and state the objective first!
