A 60-μc charge is held fixed at the origin and a −15-μc charge is held fixed on the x axis at a point x = 1. 0 m. If a 10-μc charge is released from rest at a point x = 40 cm, what is its kinetic energy the instant it passes the point x = 70 cm?.

What are the five categories of my plate

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.

Which statement best describes gravity? it is the force that repels only very small objects. it is the force that acts between objects with zero mass. it is the force that sometimes acts only on very large objects. it is the force that acts between any two objects in the universe.
