Assuming that the bridge segments are free to pivot at each intersection point, what is the tension t in the horizontal segment directly above the point where the object is attached? (figure 2)if you find that the horizontal segment directly above the point where the object is attached is being stretched, indicate this with a positive value for t. If the segment is being compressed, indicate this with a negative value for t.

In an ecosystem, marsh snails feed on phytoplankton and painted turtles feed on marsh snails. pollution has resulted in the depletion of phytoplankton. what effect would this situation likely have on the population of marsh snails and painted turtles? as phytoplankton were destroyed, the population of marsh snails would most likely then the population of painted turtles would mostly likely a. 1. increase 2. decrease 3. stay the same b. 1. increase 2. decrease 3. stay the same
