What is electroweak epoch?
A sample from a meteorite that landed on Earth has been analyzed, and the results shows that out of every 1,000 nuclei of potassium- 40 originally in the meteorite, only 125 are still present, meaning they have no yet decayed. How old is the meteorite (in yr)? (Hint: see the figure below) (Note: The half life of potassium- 40 is 1.3 billion years.)
_______ yr
I've started solving this problem, and feel like I'm on the right track, but need help when it comes to solving logarithms. Please see attached photos

- Consider the differentiated meteorites. We think the irons are from the cores, the stony-irons are from the interfaces between mantles and cores, and the stones are from the mantles of their differentiated parent bodies. If these parent bodies were like Earth, what fraction of the meteorites would you expect to consist of irons, stony-irons, and stones? Is this consistent with the observed numbers of each? (Hint: You will need to look up what percent of the volume of Earth is taken up by its core, mantle, and crust.)arrow_forwardIf you detected radio signals with an average wavelength of 68 cm and suspected that they came from a civilization on a distant Earth-like exoplanet, roughly how much of a change in wavelength (in cm) should you expect to detect as a result of the orbital motion of the distant exoplanet?
