Consider a relatively nearby, single star, that is, a star that is not a member of a binary system and has no known orbiting planets. Listed below are a few properties of this star. Classify each property as either something that we can observe or measure directly (with the aid of a telescope and instruments such as cameras or spectrographs) or something that we must infer indirectly (and hence is correct only if all of our assumptions are correct).a. colorb. parallax angle
c spectral typed. apparent brightness
e. luminosity
f. surface temperature
g. mass
h. radius

THINGS THAT CAN BE OBSERVED FROM THE USE OF TELESCOPE AND OTHER INSTRUMENTS INCLUDES

- color

- parallax angle

- spectral type

- apparent brightness

THINGS WE MUST INFER INDIRECTLY INCLUDES

- luminosity

- surface temperature

- mass

- radius

states grant a variety of local governments power to meet residents’ needs (source: apex learning). hope this !

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
