What is curvature of earth?
The Earth is a sphere. It is shaped like a sphere because gravity shapes it this way. For this same reason the moon, sun, and other massive bodies in space are also spherical.
What is the curved path an object takes when it is thrown?
In the absence of air and neglecting the Earth's curvature, the path would be part of a perfect parabola.
What are microwave ray used for?
Microwave are used to locate ships and planes, track weather systems, and determine the speeds of moving objects.They are the principal carriers of television, telephone, and data transmissions between stations on Earth and between the Earth and satellites.
Does a human body have a gravitational force?
according to the general theory of relativity gravity is created by a curvature of space. Theoritcly any object with mass would curve space thus creating a gravitational field. However the mass of a human is not significant enough to create any significant curvature of space. Further to that any curvature created by a persons mass is outweighed by the curvature created by the earth's mass. Yes. If humans had no gravity, we would be weightless, and this would make life on earth exceedingly difficult. The argument that earth has gravity doesn't address the issue. Gravity is a mutual attraction between two bodies that have mass. In order for humans to have no gravity, we would have to be completely without mass. Any object with mass has a measureable gravitational field.
What would happen if earth didn't have gravity?
If the earth had no gravity it follows that gravity would be absent from any mass. In the absence of gravity life would not exist.
What is the phenomenon where microwave signal follows earth curvature?
Microwave EM radiation travels only in a straight line - line-of-sight/point to point. Bouncing waves off of the ionosphere would accomplish this.
What is the difference between radio horizon and optical horizon?
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
Television signal cannot be received beyond a particular distance because?
curvature of earth
When a pilot flies a long distance flight - does the pilot have to descend the plane mid-flight to match the curvature of the Earth?
No. Level flight for an aircraft is not flight in a straight line (vertically) but one that follows the curvature of the earth. It is an arc that maintains the same altitude.
What are the use of microwave signals?
Microwave frequencies are generally considered to be in the region above 1000 Megahertz, (About 30 cm wavelength.) and as the gain of an antenna depends on it's size in wavelengths, it is possible to make very tightly focused beams at these wavelengths. This then allows low power transmitters to communicate over long distances by aiming a beam of energy at a receiving antenna. The disadvantage is that it is strictly line of sight, so mountains or earth's curvature will block the signal, hence microwave systems are often mounted on towers or tall buildings.
What is a satellite signal?
It's the same information-carrying signal that you'd receive from any microwave station on a tower in a network carrying telephone, television, voice, data, navigation etc. from place to place, except that this microwave repeater happens to be in an artificial satellite that's orbiting the earth.
How high above the earth do you have to go to see the curvature of the earth?
20 miles
What is terrestrial microwave technology?
Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. They are different in that satellite microwave technolgies seek to neutralize the effects of the atmosphere in the microwave transmissions. On the other hand, terrestrial micowave technologies seek the aid of atmospheric effects on microwaves to extend the range limitations imposed by the Earth's curvature. Examples of these terrestrial technologies include those used to exploit troposcattering and meteor-burst in microwave communications--not used at all in satellites. Professor Martinez

Would the earth's curvature be seen from top of Burj Dubai?
It is impossible to see the curvature of the earth from the first three layers of the atmosphere... Also, it is impossible to see the curvature of the earth from an aeroplane (which flies up to 28,000 feet) whereas the Burj Khalifa's spire reaches only 2,723 feet. Hence proved, we cannot see the curvature of the earth from the Burj Kahlifa... Ofcourse, you can go there and try it yourself...
Why do you have horizon?
Because the earth is a sphere. The horizon is the curvature of the earth (or other planet) as it falls away from you.
