The half-life for the radioactive decay of u-238 is 4.5 billion years and is independent of initial concentration. how long will it take for 10% of the u-238 atoms in a sample of u-238 to decay? if a sample of u-238 initially contained 1.5Γ10181.5Γ1018 atoms when the universe was formed 13.8 billion years ago, how many u-238 atoms does it contain today?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
