Why microwaves can be used for satellite TV communications but not terrestrail TV?

Microwaves can be used for satellite TV communications because they can travel long distances with minimal attenuation and penetrate the Earth's atmosphere effectively, allowing signals to be transmitted from satellites in orbit to ground receivers. In contrast, terrestrial TV often uses lower frequency signals that are better suited for covering shorter distances and penetrating buildings. Additionally, terrestrial TV relies on a network of ground-based transmitters that are optimized for local broadcast rather than long-range transmission like satellites. Thus, the characteristics of microwaves make them ideal for satellite communication, while terrestrial systems utilize different frequencies.


How many different stations does the XM satellite radio service offer?

Satellite Radio in an analogue or digital radio signal that is relayed through one or more satellites and thus can be received in a much wider geographical area than terrestrial FM radio Stations.


What are the eight different terrestrial animals used for food in the world?

There are far more than eight


What is the difference between terrestrial TV and satellite TV?

Terrestrial is earthbound. It is broadcast from antenna towers here on Earth. Satellite TV is broadcast by communications satellites from outer space in geosynchronous orbit. They orbit at the same rate that the Earth rotates, therefore they remain "parked" over the same geographic region, relative to the surface of the Earth they are standing still. Terrestrial TV also makes use of satellites, but rather than broadcasting directly to a customers dish, they are broadcasting specifically for re-broadcast by local network affiliates over their terrestrial antennas.


Which gas giants have more moons than the terrestrial planets?

Jupiter and Saturn have more moons than the terrestrial planets. Jupiter has over 80 moons, while Saturn has over 80 confirmed moons as well. This is far more than the terrestrial planets in our solar system, such as Earth, Mars, Venus, and Mercury, which have few or no natural satellites.


How does satellite tv compare in quality of reception to DSL?

These are two entirely different things. Satellite providers do offer internet via satellite however. Generally the DSL internet service is more reliable and faster than satellite.


Is Pluto denser than the terrestrial planets?

No. Pluto is significantly less dense than the terrestrial planets. A large portion of Pluto is made of ice, which is less dense than thr eock and metal that compose the terrestrial planets.


The most obvious difference between the terrestrial and the jovian planets is?

The most obvious difference between terrestrial and jovian planets is their composition. Terrestrial planets are rocky and dense, while jovian planets are mostly composed of gases and lack a solid surface. Additionally, jovian planets are typically larger in size and have extensive ring systems.


Is satellite internet better than other types of service?

Satellite service's chief benefit is coverage. With a satellite Internet receiver, one can typically get Internet access across the continent or across the world. However, due the the high cost of satellite transponders the bandwidth is much more limited than terrestrial service and is more expensive. In addition, due to the distance the microwave signal must travel, latencies are much higher (on the order of 7 to 13 times higher than DSL for non-LEO service providers). This can make VoIP, video conferencing, and online gaming frustrating.


Why are the temperatures of each terrestrial planet different than earth?

Their distance from the Sun as well as their atmosphere - presence or absence as well as its composition (if present)..


Why are plants under the sea a different color than land plants?

The water refracts the light so aquatic plants receive different wavelengths of light than their terrestrial counterparts. Accordingly, the plants have different pigments to trap the different wavelengths which accounts for the difference in color.
