Modern fireplaces use a CATALYTIC COMBUSTOR to burn exhaust gases.
A catalytic combustor is an attachment which allows exhaust gases to be chemically broken down to release more energy. This is how it is applicable to modern fireplaces.
The minimum coefficient of friction to avoid slippage of the coin is 0.23.
<h3>
Minimum coefficient of friction</h3>
The minimum coefficient of friction can determined from the maximum speed of the coin.
ma = μmg
mv²/r = μmg
v²/r = μg
v² = μgr
μ = v²/(gr)
μ = (ωr)²/(gr)
μ = ω²r/g
μ = (7.95² x 0.035)/(9.8)
μ = 0.23
