The relationship between a main sequence star's b-v color value and luminosity is a direct relationship.

The Hipparcos satellite measures the distances between hundreds of thousands of stars. It measures the magnitude of each stars through two filters which are, a blue filter, yielding for B magnitude (for blue) and a greenish filter, yielding a V magnitude (for visual).

The difference between the B and V magnitude of star is (B-V) color , or sometimes just "color" in short. The wavelength of light where the star is related to the star's temperature, i.e., the hotter the star the more blue it is and the cooler the star the more red it is.

Straighterline the lowest or most basic needs in maslow's classification system are called _______ needs.
Keith_Richards [23]

Straighterline the lowest or most basic needs in maslow's classification system are called <u>"biological"</u> needs.


Maslow's hierarchy of needs is a motivational theory in psychology containing a five-level model of human needs, frequently delineated as progressive levels inside a pyramid.  

"Biological/Physiological" needs are the physical prerequisites for human survival. In the event that these necessities are not met, the human body can't work and will eventually fall flat. Physiological necessities are believed to be the most imperative and they are needs that ought to be met first.

Suppose you are the Tourism Minister of Bangladesh- Give a specific plan for becoming a major tourism specialist in 2030?
Elena-2011 [213]

Answer and Explanation:

To become a tourism specialist you need to start a long journey of courses. The first course should be a higher level course related to tourism, travel and management. In addition to higher education, it is necessary to start a series of internships that promote professional experience and allow the establishment of contacts and the opportunity to work with big names in tourism and absorb all the knowledge that they can promote and that will be of great help for the future .

Higher education is not the only course that must be taken, it is necessary to take several complementary courses, which allow the professional to become as comprehensive as possible and have mastery of several different points within the fields that make up tourism. The search for complementary courses should follow the professional's entire life and it is these courses that will make the individual a specialist in tourism.
