Does a satellite in a geostationary orbit move across the sky from east to west?

No. A geostationary satellite appears to be stationary in the sky, which means not moving. This is a big part of the reason why it is referred to as a geo'stationary' satellite.


Do satellite travel the same direction as the earth?

Yes - usually. The reason for this is that doing this requires less energy to launche them, since the launching rocket will use the Earth's rotation.


MAPEH what is arts?

ARTS is a radiative transfer model for the millimeter and sub-millimeter spectral range. There are a number of models mostly developed explicitly for the different sensors. The basic principle for the development of ARTS is to provide a code that can be applied for many different applications concerning radiative transfer calculations in the microwave region. For this reason much emphasis has been placed on modularity, extendibility, and generality.


How do satellites move in orbit?

Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx

What is lateral inversion?

Lateral inversion is the reversal of an object when the image is formed in a flat mirror. This reversal is only in the direction perpendicular to the surface of the mirror. However, the effect is often seen by a person as a "left-right" reversal with the "front-back" reversal not noticed. That's the reason it's called lateral inversion. "Lateral" means sideways.

Are the spectral line always in the same order?

The arrangement of the spectral colors are determined by how the human eye and brain work. There is no clear reason to believe that different people or animals see the spectrum the same. In fact it is easy to show that they don't.

Why inversion of sugar is done in pharma industry?

Sucrose in syrup or other liquid formulations on storage converted into glucose and fructose(1:1) with lose of a molecule of water this is called inversion of sugar and solution becomes concentrate this is reason instead of sucrose inverted sugar syrup is used in formulation


In To My Dear Loving Husband the main reason Bradstreet uses inversion is to?

In "To My Dear and Loving Husband," Bradstreet uses inversion to emphasize the deep love and admiration she has for her husband, placing his qualities before her own in order to elevate and honor him. This rhetorical device helps convey the intensity of her feelings and her belief in the strength of their relationship.


Can a person renting you a room in North Carolina disconnect your satellite for nonpayment of rent when there is no lease?

No lease = no protection for either party. You're lucky your satellite just got disconnected instead of finding your stuff out on the lawn. More generally, if you don't have a contract specifying that you get satellite, then yes, your landlord can disconnect it for any reason he likes, or even for no reason at all.


Why satellites are placed at an altitude of 36000 km is there any reason for such an long altitude pls answer thanks in advance?

The closer to the Earth, the faster the orbit; this is basic math, as determined Johannes Kepler centuries ago. The higher the orbit, the slower the satellite goes. IN 1947, science fiction writer Arthur C. Clarke wrote an article and a story based on the curious coincidence that if a satellite were placed in an equatorial orbit 23,000 miles (or 36,000 km) up, the satellite would orbit the Earth at precisely the speed that the Earth itself turns. The satellite would appear to be suspended, motionless, in the sky! Since an Earth-based antenna would not need any rotors or pointing mechanisms to track an unmoving satellite, the antenna could be made larger - MUCH larger. We now call that orbit "geo-synchronous", and that's where we park communications satellites, and TV satellites. It didn't occur to Arthur Clarke to patent his invention; and because he did not, the satellite communications revolution proceeded unimpaired by patent lawsuits.


What was the reason for Internet?

The reason for Internet was to facilitate military communications. The internet has evolved since then and has become the main mode of communication and handling business activities among other things.


Why a precise geo stationary orbit can not be obtained?

Because the geostationary orbit round the Earth is perturbed by gravity from the Sun and Moon. The biggest effect is to change the orbital plane of the geostationary satellite so that, after a while on station, in 24 hours it appears to move up and down slightly. For that reason communications satellites need motors and fuel to correct the orbit from time to time.


Why does People Opt for Satellite TV to PC?

The reason why people choose to have Satellite TV for PC is because of the following:· They can't afford to pay a monthly subscription· They have high speed internet connection and doesn't want to pay for additional satellite tv subscription where they can watch movies on their computer· They don't have satellite TV services in their location· Apartments don't permit them to have satellite dish installed on their roof or their landlords don't want them to subscribe to any subscription like satellite tv services.· They want to watch movies from another country which satellite tv services don't have
