An electrically neutral molecule is collinear with (and located between) two charged particles, one carrying a charge of +3.56 μC and the other carrying a charge of -1.05 μC. The center of the molecule is 2.57 μm from each particle. Part A If the vector sum of the electric forces exerted on the molecule is 45.0 nN , what is the polarizability of the molecule? Express your answer using two significant digits. α =

Describe the five characteristics of life, and list several nonliving things that possess at least two of these characteristics. Explain how an atom relates to the biosphere by describing the levels of organization. Why is a cell, and not an atom or a molecule, considered the basic unit of life? Draw and explain the relationship between producers and consumers (including decomposers). How does a homes’ air conditioning system illustrate homeostasis? Describe the main differences between asexual and sexual reproduction. Why...
