The second law of themodynamics says that whenever energy is converted from one form to another in a physical or chemical change a. heat is absorbed b. light is produced c. the second form of energy will always be kinetic d more energy will be present in the second form e. we end up with lower-quality or less useable energy than we started with

Which is the best predictor of the radioactive nature of an isotope? o the proton-to-electron ratio the neutron-to-proton ratio o the neutron-to-electron ratio the electron-to-proton ratio

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
