How many significant figures are in the following:
41)    0.23400m		42)   23400		43)  0.0002356


______44. Science fiction often uses nautical anologies to describe space travel.
If the starship U.SS.S. Enterprise is traveling at warp factor 1.71,
 what is its speed in knots? (given 1.71 warp = 5.00times the speed of light, 
speed of light = 3.00x108m/s,  1.00 knot = 2000 yd/hour.  2.54 cm = 1.00 inch. 


________45.A scientist obtains the number 1250.37986 on a calculator.
