Amajor artery with a cross sectional area of 1.00cm^2 branches into 18 smaller arteries, each with an average cross sectional area of 0.400cm^2. by what factor is the average velocity of the blood reduced when it passes into these branches

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

Properties seen when one one substance changes to another are known as properties

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
