Suppose that an electron and a proton are placed at a distance of 1.2nm away from each other (about 10 times the radius of a hydrogen atom). (a) How much is the Coulomb force between the electron and the proton? (b) Under this Coulomb force alone, how much is the acceleration of the electron towards the proton (in m/s2 )? (Google for the missing information.) (c) If the electron is instead placed on the edge of the supermassive black hole...

When DNA is compacted by histones into 10-nm and 30-nm fibers, the DNA is unable to interact with proteins required for gene expression. Therefore, to allow for these proteins to act, the chromatin must constantly alter its structure. Which processes contribute to this activity? a. nucleotide removal b. hydrolysis of DNA molecules where they are wrapped around the nucleosome core c. DNA coiling at or around H1 d. accessibility of heterochromatin to deacetylase enzymes e. acetylation of histone proteins What...

An electron has a de Broglie wavelength of 235 nm .What is the speed of the electron? --------------------------------------------------------------------- How much energy is contained in 1 mol of γ-ray photons with a wavelength of 2.43×10−5 nm . ? ------------------------------------------------------------------------ In a technique used for surface analysis called auger electron spectroscopy (AES), electrons are accelerated toward a metal surface. These electrons cause the emissions of secondary electrons-called auger electrons-from the metal surface. The kinetic energy of the auger electrons depends on the...

What happens to the acceleration of a system when the mass of the system increases if the force stays constant? What happens to the speed when the force increases but the mass stays constant? You double the force on a system but the acceleration is still the same. What must have happened to the mass? What does μ represent? What are its units? Which surface would you expect to have the larger coefficient of friction, ice or asphalt? Why? What...
