What is the difference between the energy of spring a, stretched 0.6 meters, and spring b, stretched 0.3 meters, if they have the same spring constant? a. spring a has more potential energy than spring b. b. spring a has less potential energy than spring b. c. springs a and b have the same potential energy. d. springs a and b have the same kinetic energy.

Why is retrograde motion an apparent motion

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
