8
kg in 15 days
Step by step explanation
Earth picks dust from atmosphere in 8 days= 6.4\times 10^7kg6.4×10
7 kg
So by unitary method
Earth picks dust from atmosphere in 1 day = \dfrac{6.4\times 10^7}{8} = 0.8\times 10^7kg
8
6.4×10
7
=0.8×10
7
kg
Earth picks dust from atmosphere in 15 days
=0.8\times 10^7kg \times 15 = 12\times 10^7 = 1.2\times 10^ 8kg=0.8×10
7
kg×15=12×10
7
=1.2×10
8
kg
Hence, the earth picks up 1.2\times 10^ 8kg1.2×10
8kg in 15 days
