Our science club built a catapult out of craft sticks, glue, and a rubber band. We wanted to determine what size rubber band was best for launching a gumball across the classroom. If the rubber band was too small, the gumball wouldn’t travel very far. If it was too big, it would be too loose to work well. We found that a rubber band with a circumference of 11 cm shoots the gumball the farthest Independent variable:

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
