If we model the Earth-cloud system as a huge capacitor, what are the capacitance of the Earth-cloud system, the charge stored in the "capacitor", and the energy stored in the "capacitor"?
It is proposed that the new design be implemented only if sample data strongly indicates a reduction in true average braking for the new design. A sampe of 36 observations of the new design resulted in a sample mean of 114.8 ft and a standard devi
