Assigning value to parts of our environment based on their economic worth to humans is to assign:

A claim that wearing a copper bracelet cures arthritis is an example of pseudoscience primarily because:

Why don’t scientists ever consider any theory to be ‘absolutely 100% proven’?

You go to a doctor who says you may have cancer or just the flu and recommends immediately beginning cancer treatment. What principle of Scientific Literacy did the doctor violate?

A telephone survey asks respondents how much they spent on groceries “in the last three months.” Reported totals average more than 30 percent above what store scanner data indicate for the same period. This overreporting pattern is most consistent with:

A judgment sample that relies on the researcher’s ability to locate an initial set of respondents with the desired characteristics is a:

A researcher must code responses to the open-ended item “What do you like about our store?” Which practice best manages coder subjectivity?

SHOW ALL WORK FOR FULL CREDITUse k = 8.99 × e+9 N·m²/C², ε₀ = 8.85 × e-12 C²/(N·m²), e = 1.60 × e-19 C. Use mₑ = 9.11 × e-31 kg and mₚ = 1.67 × e-27 kg. An electron is in a uniform electric field of magnitude 2.50 × e4 N/C. What is the magnitude of its acceleration, in units of e15 m/s²?

SHOW ALL WORK FOR FULL CREDITUse k = 8.99 × 10^9 N·m²/C², ε₀ = 8.85 × 10^-12 C²/(N·m²), e = 1.60 × 10^-19 C. A +3.0 μC point charge is fixed in place. How much work must an external agent do to bring a +5.0 μC point charge slowly from very far away to a point 0.25 m from the fixed charge, in J?

SHOW ALL WORK FOR FULL CREDITUse k = 8.99 × e+9 N·m²/C², ε₀ = 8.85 × e-12 C²/(N·m²), e = 1.60 × e-19 C.A very long, straight line of charge carries a uniform linear charge density of +[L] nC/m. What is the magnitude of the electric field [r] cm from the line, in N/C?
