Because it would work.
what strengthens/weakens aluminiumWith most pure metals (and aluminium is a good example), bending first hardens it, then weakens it.
what is the difference from aluminium used on cans vs aluminium used on alloy wheels(mag wheels)Aluminium cans are designed to be as thin as possible - just enough to withstand the pressure of the gas inside, and the weight of cases of cans piled on top of each other.
Nice analogy.Quote from: RobCIs there a simpler explanation?Probably the simplest equation to calculate the speed of light in a vacuum:
c = 1/√(ε0μ0)
- c: velocity of light in a vacuum
- ε0: permittivity of a vacuum
- μ0: permeability of a vacuum

This is just as simple as the equation for the speed of a vibration on a string (eg a guitar string):
v = √(T/ρ)
- v: velocity of a wave in the string
- T: tension of the string
- ρ: density of the string

For more information:
at a temperature of 0.1C, you can have a container with liquid water and water vapor at a pressure around 0.6% of normal Earth atmospheric pressure (if I am reading this correctly...).Close...

On average it takes a 100 days fpr the pandemic to develop into a big problem and then 100 days to decline.How do you know?
