tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator. tafu models its position with the function p(t)= t2 t – 1 where t>1. in the limit calculations below, if you need to use -[infinity] or [infinity], enter -infinity or infinity.

Why do you need to classify the size of a particle

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
