Topology question:
Show that a function f : ℝ → ℝ is continuous in the ε − δ
definition of continuity if and only if, for every x ∈ ℝ and every
open set U containing f(x), there exists a neighborhood V of x such
that f(V) ⊂ U.

1. What is the mechanism of action for each of the antibiotics used in this experiment?”
2. If a population of bacteria evolves resistance to penicillin, are these bacteria more likely to be also resistant to ampicillin or kanamycin? Explain your reasoning.”

1) During this distillation experiment, a student collects a 10.00 mL fraction consisting of 70% ethyl acetate and 30% n-butyl acetate (by volume). What is the mole fraction of n-butyl acetate in this sample?
2) Suppose you used a shorter distilling column in this fractional distillation experiment. Would you expect to obtain a better or worse separation between the two esters explain your answer.

I have to do an experiment/ demonstration for my PHY251 class (Calculus based physics). I am only allowed to do it on one of the following topics: Vectors, Accelerated motion, Centripetal force, Free fall, projectile motion, Inertia, Equilibrium, Friction, Orbits, Tides. Does anyone have any ideas for a cool demonstration? Please provide instructions for the demonstration/experiment. Thank you in advance.

Assume you are performing the calibration step of Experiment 8 and you begin with 20 g of water at 20 oC and 20 g of water at 80 oC. After adding the two portions of water into your calorimeter setup and following the procedure outlined in the experiment, you determine the temperature of the mixed portions of water to be 45 oC. What is the heat capacity of the calorimeter? Assume room temperature is 25 oC.
