The adult massasauga, also known as the swamp rattler, is a stout-bodied snake with a broad head. It measures 18-40 inches (45-100 cm) in length. Average length is 27.5 inches (70 cm).assasauga rattlesnakes range from central New York and southern Ontario west to the prairies of Iowa and Missouri. The eastern massasauga is strongly associated with wetlands across most of its range. Wet prairie is the preferred habitat in the west, bogs and swamps in the east.
Zeptometer is a length measurement unit. A zeptometer (zm) is a derived metric measurement unit of length. The metric unit prefix zepto means one sextillionth, or one (1) with twenty (20) nulls in front of it, i.e. 0.000,000,000,000,000,000,001 or 1Ã10 -21. That makes one zeptometer equal to one sextillionth of a meter.
An exhaust gas temperature gauge (EGT gauge) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes.By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio. At a stoichiometric air-fuel ratio, the exhaust gas temperature is different from that in a lean or rich air-fuel ratio.At rich air-fuel ratio, the exhaust gas temperature decreases due to the cooling effect of the fuel.t a stoichiometric air-fuel ratio, the exhaust gas temperature is different from that in a lean or rich air-fuel ratio.
