A machine part is vibrating along the x-axis in simple harmonic motion with a period of 0. 27 s and a range (from the maximum in one direction to the maximum in the other) of 3. 0 cm. At time t = 0 it is at its central position and moving in the +x direction. What is its position when t = 55 s?.

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
