Aheavy rainstorm dumps 1.0 cm of rain on a city 4 km wide and 8 km long in a 2-h period. part a how many metric tons (1 metricton = 103 kg) of water fell on the city? (1 cm3 of water has a mass of 1 gram = 10-3 kg.) express your answer using o

The mass of water in metric tonnes equals metric tonnes.

Step-by-step explanation:

To compute the mass of the rain water we intially need to compute the volume of the water that is collected in the city.

Since it is assumed that the city is flat we can obtain the volume of the rainwater as

Now since it is given that the density of water is 1 gram per cubic centimeter thus we have

Thus the mass of the calculated volume of water becomes

Now since we know that 1 metric ton equals 1000 kg thus the total weight in metric tonnes equals

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
