From the perspective of a person at the surface of the Earth, how does the special theory of relativity explain how muons created high in the atmosphere make it to down to the surface, when it seems like they should decay before they get there?

ByAdmin July 27, 2021

The person observes the muon’s velocity to speed up by the Lorentz factor, so that it gets down to the surface of the Earth more quickly than it otherwise would.

The person observes the muon’s internal “clock” running more slowly than when the muon is at rest, due to time dilation, so the moving muon stays intact longer than it otherwise would.

The person observes the distance from the upper atmosphere to the surface of the Earth to be shortened, due to length contraction, so the muon doesn’t have to travel as far as it otherwise would.

You expect that a project will bring in $15,000 USD in revenue per year. You estimate it will cost $10,000 up front. You also estimate costs of $100 per month for the first 12 months, which equals $1,200 per year. Using the formula (G-C) ÷ C = ROI, how would you calculate the project’s return on investment (ROI) after the first 12 months?
