Calculate the total mass of water in kg on Earth's surface from the following data: total planetary surface area: 510,066,000 km

irinina [24]

Answer:

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

Explanation:

Total planetary surface area = T = $510,066,000 km^2$

Total land area of planet = L = $148,647,000 km^2$

Total water area of planet = W

T = L + W

$510,066,000 km^2=148,647,000 km^2-W$

$W=510,066,000 km^2-148,647,000 km^2=361,419,000 km^2$

Volume = Area × Depth

Volume of water on earth = V

V= $361,419,000 km^2\times 100 km^=36,141,900,000 km^3$

$km^3=10^{12} L$

$V=36,141,900,000 km^3=36,141,900,000 \times 10^{12} L$

Total mass of total water on the earth = M

Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L

1 g - 0.001 kg

1 mL = 0.001 L

$D=\frac{M}{V}$

$M=D\times V$

$M =1 kg/L\times 36,141,900,000 \times 10^{12} L=3.61419\times 10^{22} kg$

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

16. If planet A and planet B are circling the sun and if planet Bis 10 times as far as planet A is to the sun. Then which, plane

slega [8]

Answer:

Planet B

Explanation:

Planet B will take more to time to complete its revolution because it is farther to the sun. The shorter planet completes its revolution faster due to its short orbit around the sun. This implies that planets that are close to the sun have shorter time to complete their revolution but those far away will take more than usual.

How do you understand areas of the world, such as Bantu Africa and North America, that did not generate “civilizations”? Do you

lions [1.4K]

We can not say that this areas are not civilized or to call them backwards. We may call them different. We can take for example the uses of animals in order to expand the commerce of their area. If we research about the use of camels, for example, we could see that it gained an special place within those who wanted to travel through many difficult areas like deserts. So in the case of camels they were not backwards, they used a different method to obtain success
