Every star is part of a constellation and is assigned a Greek letter within the constellation. Many stars still bear ancient Ara
Andru [333]

Answer:

All 88 constellations are based on figures that originated in Greek and Middle Eastern mythology. (<em>Correct</em>)

The α star in a constellation is usually brighter than the β star. (<em>Correct</em>)

All stars are part of some constellation. (<em>Correct</em>)

The modern constellations have English names rather than Latin like the ancient ones. (<em>Correct</em>)

Explanation:

Constellations were grouped by different civilizations as mean to be oriented when they were making observations of the sky (they could see as maps of certain regions). Each constellation is an arrangement of several stars in a specific figure (animals, mythological characters and objects), things that were important for that civilization.

The letter \alpha is given to the brightest star in a constellation while the other letters of the Greek alphabet are assigned to the other stars that belong to that specific constellation according to their brightness. For example in the Orion constellation the brightest star is Betelgeuse so it is classified with an \alpha; \beta to Rigel, the second in brightness and so on. That classification system was established by the astronomer Johann Bayer in 1603.

The modern constellations have English names, for example the constellations of Telescopium, Fornax, Sculptor, Chamaeleon, among others.

As constellations represent maps of different regions in the sky, any star will be related with them. For that reason is correct to say that all stars are part of some constellation.

A 0.47 kg mass is attached to a spring with a spring constant of 130 N/m so that the mass is allowed to move on a horizontal fri
Sidana [21]

Answer:

F= 15.6 N,   a= 33.2 m/s^2

Explanation:

mass= m = 0.47 kg

spring constant= k = 130N/m

spring compression = x = 0.12 m

a).

force on the mass= F = k*x

F = 130 * 0.12 N

F= 15.6 N

b).

Acceleration of mass= a=?

F= ma

a=F / m

a= 15.6/ 0.47 m/s^2

a= 33.2 m/s^2
