Two charges 1 = +2. 0 and 2 = +2. 0 are placed symmetrically along the x-axis at x = ±3. 0 cm. Consider a charge 3 = +4. 0 and mass 10. 0 m moving along the y-axis. If 3 starts from rest at y = 2. 0 cm, what is its speed when it reaches y = 4. 0 cm?.

This graph represents four ecosystems. each ecosystem has a different number of species, adding to its biodiversity. different colors represent different species. which statements correctly summarize the data depicted by the graph? 1. ecosystem d has more biodiversity than ecosystem c. 2. ecosystem b has more biodiversity than all the other ecosystems. 3. ecosystem a has more biodiversity than ecosystem b but less biodiversity than ecosystem c. 4. ecosystem b has more biodiversity than ecosystems c and d but less biodiversity than ecosystem a. 5. ecosystem a has more biodiversity than ecosystem c but less biodiversity than ecosystem b.
