If a star system 30 parsecs distant is found to be broadcasting intelligent radio signals, then their news is already approximat

IrinaK [193]

Answer:

97.85 years, approximately.

Explanation:

Light travels at a <em>constant</em> speed of 186,000 mi/seg or 300,000km/seg accross the Universe (in vacuum conditions). Radio waves are also part of the electromagnetic spectrum, and they also travel at the same speed as Light does.

A light-year is a measure of the distance that Light travels during a year, that is, 5.88 trillion miles. Light travels the same distance per year because its speed is <em>constant</em>, and this is an excellent property that scientists take advantage to measure distances.

A parsec is 3.26 light-years (19 trillion miles), and (a very important datum to solve this question) one light-year is 0.306601 parsec, that is, in a year Light travels 0.306601 parsec at a <em>constant</em> speed. The same would happen with intelligent radio signals broadcasted from a distant star system.

So, considering all these facts, it is a matter of proportions to solve this question (mostly because speed of Light is constant):

$\frac{1 year}{0.306601 parsec} = \frac{X years}{30 parsecs}$

$x =\frac{1 year * 30 parsec}{0.306601 parsec}$

$x = \frac{30}{0.306601} years$

x = 97.84704 years or,

x = 97.85 years, approximately.

In other words, Light spends 97.85 years (terrestials) to travel 30 parsecs.

Likewise, radio waves travel at the same speed, so they spend the same years (97.85 years) travelling across the Universe to be finally detected by a radiotelescope located, for instance, here, in our planet.

Finally, the star system broadcasted intelligent radio signal with 'news' that are already approximately 97.85 years old'.

Ira Lisetskai [31]

Answer:

SURVEILLANCE-SPECIFIC DESIGN.

Explanation:

Defensible space offers a series of architectural guidelines that can be used in the design of new urban residential complexes to promote both the residential group’s territorial claim to its surroundings and its ability to conduct natural surveillance. The designs are: site interrelationship design, site design, street design and surveillance-specific design.

Surveillance-specific design can be used to increase general visibility by providing adequate lighting, by reducing or eliminating physical barriers to visibility, and by the visibility-promoting location of key areas (entrances, lobbies, elevator waiting areas, parking areas e.t.c.) so as to be directly visible from as many viewpoints as possible.

Since the data center designer requested additional lighting for the entrance to the data center as well as the removal of a object which is blocking security's view of the entrance, then it is an example of SURVEILLANCE-SPECIFIC DESIGN.
