What is the work needed for a 65kg person to climb through 4.0m surface of the earth?
mgh=65*4*10=2600J
How did Sir Charles Lyell's work help scientists?
by providing an understanding that most changes on earth's surface happen slowly
Since the astronaut is in outer space how does the heart work without the earth's magnetic field?
There are two parts to this: First, the Earth's magnetic field extends beyond its surface. Second, and more importantly, the heart does not rely on an external magnetic field in order to work.
How do weathering and erosion work together to shape Earth's surface?
Wheathering breaks down rocks and erosion transport it away by wind,rivers,sea
What term is used to describe incoming solar radiation?
25% is absorbed by clouds.25% is reflected by clouds.45% is absorbed by the earth's surface.5% is reflected by the earth's surface.So 50% reaches the surface of the earth (But 5% of that is reflected).
What is endogenic?
endogenic forces have their origin deep down in the earth's interior and they work from below
What is the distance from the earths surface to Earth's crust?
i hate this home work
What are the telescopes that work on earth's surface?
X-ray telescopes are used to study mainly the Sun, stars and supernovas. X-ray telescopes work better at very high altitudes on the Earth's surface.
What are the complex processes which work to break down the earth's surface called?
exogenous
What aspects of the martian environment might limit or affect the scientists' ability to do this kind of work outside on the martian surface?
Mars does not have a breathable atmosphere, which makes it difficult to work on the surface.
Why doesn't earth's surface resemble that of mercury?
There are a number of reasons. The key to it is that Earth has a substantial atmosphere while Mercury does not. Earth's atmosphere allows presence of liquid water, which in turn allows Earth to support life. Wind, water, and life are important forces in eroding and, in some cases, building Earth's surface features. Water also works its way into Earth's mantle, turning part of it into the sof asthenosphere, which no other known planet has. This, and Earth's hotter interior allows for plate tectonics, which slowly but continuously reshape Earth's surface. So Earth's surface ins constantly subjected to continuous change as old features are destroyed and new ones arise. Mercury has none of these traits, and its only substantial surface features are impact craters. With no active forces at work on Mercury, these craters will remain unaltered for billions of years.
How does the mass an object affect it acceleration?
When an object is falling in a gravity field, its mass does not affect its acceleration. If under the influence of friction then it takes more energy to accelerate it the larger mass it has, here on Earth. The larger the mass the more potential it has to do work if it is above the surface of the earth than a smaller mass. But in turn, to get it to the higher point more work must be done for a larger mass than a smaller mass.
What is ground effect and how does it work?
The result of the interference of the surface of the Earth with the airflow patterns about an airplane.
How does a submersible pump work?
As the name suggests submersible pumps work underneath the surface of the earth. Unlike regular pumps they push water or other liquids to the surface instead of sucking it up from above the surface.
How much would you weigh on Super-Earth?
Please tell me the acceleration of gravity on the surface of Super-Earth, and I'll be happy to work it out for you.
What does geography describe?
Geography is the science of the study of the surface of the Earth. It is the physical features of the land, especially the surface features like lakes, mountains, ravines, etc.
How convection currents work in the mantle?
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.
