For a spring-mass oscillator, if you triple the mass but keep the stiffness the same, by what numerical factor does the period change? that is, if the original period was and the new period is , what is ? it is useful to write out the expression for the period and ask yourself what would happen if you tripled the mass.

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
