Science has been said to be like the process of picking at loose threads. The 50 years from 1895 through 1945 showed huge advances in the sciences. These advances include fundamental discoveries of the nature of matter, how to access the energy within the atom , and numerous other threads of knowledge. Where do you see science going in your lifetime? Be sure to include comparisons to the discoveries that led to the modern model of the atom

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wavelength of 480 ? the index of refraction of the film is 1.34, and there is air on both sides of the film. express your answer in nanometers. hint 1. how to approach th

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
