I believe the answer is "The new theory is an explanation accepted worldwide."
The variable is the disinfectant that is used, because there different ones being used
Insulators maintain temperatures better
If resistors are connected in series then total resistance=2+2+2+2+2
=10 watt
if connected in parallel then total resistance,1/R=1/2+1/2+1/2+1/2+1/2
1/R=5/2
So R=2/5
R=0.4w
The speed of the car was exactly 125 km per 2 hours.
In a more familiar unit, 125km/2hr = 62.5 km/hr.
