The burden of man-made aerosol sulfate in the earth's atmosphere, in grams per square meter, is b(x, n) = xn a where x is the total weight of aerosol sulfate emitted into the atmosphere per year and n is the number of years it remains in the atmosphere. a is the surface area of the earth, approximately 5.1 × 1014 square meters.† (a) calculate the burden, given the 1995 estimated values of x = 1.5 × 1014 grams per year, and n = 5 days. (round the answer to three decimal places.)

Burden is approximately 0.004 grams per square meters.          

Step-by-step explanation:

We are given the following information in the question:

Burden, grams per square meter is given by:

where x is total weigth, n is the number of years and A = square meters

We are given that

x = grams per year

n = 5 days =

Calculation:

Hence, burden is 0.004 grams per square meters.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
