A uniform stick can be balanced on a knife edge 10cm from one end when a mass of 200g is hung from that end. When the knife edge is moved 5cm further from that end, the 200g mass has to be moved 8.75cm from the knife edge to obtain balance. Find the length of the stick and its mass​

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.
