Answer:
The total mass of water in on Earth's surface is
.
Explanation:
Total planetary surface area = T = ![510,066,000 km^2](https://tex.z-dn.net/?f=510%2C066%2C000%20km%5E2)
Total land area of planet = L = ![148,647,000 km^2](https://tex.z-dn.net/?f=148%2C647%2C000%20km%5E2)
Total water area of planet = W
T = L + W
![510,066,000 km^2=148,647,000 km^2-W](https://tex.z-dn.net/?f=510%2C066%2C000%20km%5E2%3D148%2C647%2C000%20km%5E2-W)
![W=510,066,000 km^2-148,647,000 km^2=361,419,000 km^2](https://tex.z-dn.net/?f=W%3D510%2C066%2C000%20km%5E2-148%2C647%2C000%20km%5E2%3D361%2C419%2C000%20km%5E2)
Volume = Area × Depth
Volume of water on earth = V
V= ![361,419,000 km^2\times 100 km^=36,141,900,000 km^3](https://tex.z-dn.net/?f=361%2C419%2C000%20km%5E2%5Ctimes%20100%20km%5E%3D36%2C141%2C900%2C000%20km%5E3)
![km^3=10^{12} L](https://tex.z-dn.net/?f=km%5E3%3D10%5E%7B12%7D%20L)
![V=36,141,900,000 km^3=36,141,900,000 \times 10^{12} L](https://tex.z-dn.net/?f=V%3D36%2C141%2C900%2C000%20km%5E3%3D36%2C141%2C900%2C000%20%5Ctimes%2010%5E%7B12%7D%20L)
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}](https://tex.z-dn.net/?f=D%3D%5Cfrac%7BM%7D%7BV%7D)
![M=D\times V](https://tex.z-dn.net/?f=M%3DD%5Ctimes%20V)
![M =1 kg/L\times 36,141,900,000 \times 10^{12} L=3.61419\times 10^{22} kg](https://tex.z-dn.net/?f=M%20%3D1%20kg%2FL%5Ctimes%2036%2C141%2C900%2C000%20%5Ctimes%2010%5E%7B12%7D%20L%3D3.61419%5Ctimes%2010%5E%7B22%7D%20kg)
The total mass of water in on Earth's surface is
.
It is true that the rainfall that happens in savannas especially in summer time reaches to only half of the annual rainfall. Isolated trees and some types of shrubs are found in savanna. The precipitation rate received by savannas per year is about 30 to 50 inches.
The answer is I. 25 meters.
False. US territories in the Pacific do not include the 2 countries mentioned. The US established diplomatic ties with Vanuatu and Tonga. However, its territories in the Pacific include only Samoa, Guam, Puerto Rico, Northern Mariana Islands, and <span>United States Virgin Islands.</span>
<h2>Answer:</h2>
Balanced forces/Resultant force/ Newton's first law/law of inertia.
<h3>Explanation:</h3><h3>Balanced forces/Resultant force/ Newton's first law/law of inertia:</h3>
It says that each article will remain in its state of rest or similar motion in a straight line except a resultant force works on it. It is known as the law of inertia.
The inertia of the body is the hesitation of the target to alter its state of peace or movement.
The inertia of an article depends on its size. The greater the body, the greater the inertia. It shows it is difficult to start moving, stop, slow down, speed up or change direction. Force is required to overcome inertia.
