The passive earth pressure occurs when when a wall or plane moves towards earth. This will create additional pressure where as in the case of active pressure wall moves away from earth and it will reduce the pressure on the wall. From the co-efficient of active earthpressure and passive earthpressure,i.e
Ka = 1-sin( phi)/1+sin( phi)
Kp = 1+sin( phi)/1-sin( phi where phi is the angle of internal friction of soil.

How much atmospheric pressure is exerted on one square inch of earth?
14.7 pounds. Atmospheric pressure is 14.7 pounds per square inch Keep in mind that unless air is trapped you do not feel this as pressure is equalized
How many times greater is the mass of Earth than the mass of an electron?
The mass of the Earth is about 6x1024 kg The mass of an elecron is 9x10-31 kg Divide the first by the second to get the answer: The Earth is about 6.5x1054 times more massive. 6,500,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
What is 1543 copernicus's discovery led to greater understanding of the universe?
He said that sun was the center of the universe and that the earth and all the other planets orbit around it.
Which distance is greater The distance between the North and South poles The distance around the Tropic of Capricorn The distance around the Equator The distance around the Tropic of Cancer?
== == The perimeter of the equator is the greatest because the earth is a flattened sphere shape due to the influence of centrifugal force - a result of its rotation. The tropic of Cancer is slightly greater than the Tropic of Capricorn as there is a majority of continental land in the north. Land has a higher elevation than sea and to go around it you have to go to a higher elevation (radius) which means a greater perimeter. The north south distance is the least as it is a straight line.
Is the earth square?
No. The Earth is round!
What is the Difference between an active earth pressure and passive earth pressure?
When the wall moves away from the backfill, the earth pressure on the wall decreases. This minimum pressure is called active earth pressure. On the other hand if the wall moves towards the backfill, the earth pressure increases. This maximum pressure is called passive earth pressure.
How active satellite differ from passive explain with an example?
Active satellites are equipped with their own power source and are capable of generating and transmitting signals, whereas passive satellites rely on reflecting or enhancing signals sent from Earth. An example of an active satellite is a communication satellite that amplifies and retransmits signals, while an example of a passive satellite is a GPS satellite that reflects signals back to Earth for navigation purposes.
Difference bitween active and passive satellite?
An active satellite has its own power source to transmit signals, while a passive satellite reflects signals back to Earth. Active satellites can amplify and process signals, making them more efficient in communication. Passive satellites are simpler in design and are often used for tasks like Earth observation.
How does the pressure compare to uranus of earth?
The pressure on Uranus is much greater than on Earth, reaching up to millions of times Earth's atmospheric pressure. This is due to the thick layers of gas in Uranus's atmosphere and its large size, which leads to greater gravitational forces compressing its atmosphere.
How does pressure change as you go from the surface toward the center if the earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
How does pressure change as you go from the surface toward the center if earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
Basic Difference between Active and passive Satellite System?
An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.
How many more times is the atmospheric pressure in Jupiter's core greater than the atmospheric pressure at the earth's surface?
Earth's atmospheric pressure is measured as 1 bar. Jupiter's atmospheric pressure is 100 million bars. Therefore, it is 100 million times greater
Why is the pressure in the center of the earth greater than the pressure in the mantle?
The pressure in the center of the Earth is greater than in the mantle because the weight of the overlying rock and materials in the mantle add to the pressure as you move towards the core. In the mantle, the pressure is still significant but not as high as in the core due to the distance from the center of the Earth.
Why does the inner core receive the greatest amount of pressure?
There is pressure within the earth due to the overlying material that the earth is formed from. The deeper within the earth you go, the greater the amount of overlying material pushing down due to gravity and so the greater the pressure. As the inner core has the largest amount of overlying material pushing down upon it, it experiences the greatest pressure.
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
Neptune's atmospheric pressure is about 10 times greater than Earth's atmospheric pressure. Neptune's strong gravitational pull compresses its atmosphere, leading to much higher pressure levels compared to Earth.
How can pressure differences in Earth's atmosphere contribute to winds?
Pressure differences in Earth's atmosphere create areas of high and low pressure. Air flows from high pressure to low pressure, creating wind. The greater the pressure difference between two areas, the stronger the resulting winds will be.
