Map Sapling Learning macmilan learning If your front lawn is 24.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1450 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? Assume an average snow flake has a mass of 2.00 mg. Number kg/h
Expert Answer
Answer
area of front lawn = 24*20 = 480 ft2
in each square feet, 1450 new snow flakes every minute
So, snow flake rate = 480*1450 = 696000/min = 696000*60/hour = 4.176*107/hour
each snow flake weight = 2 mg = 2*10-3 g = 2*10-6 kg
So snow flake rate = (4.176*107)*(2*10-6 kg)/hour = 83.52 kg/hour
in one hour, 83.52 kg snow flake accumulated
