Which star do you think is the densest: Antares, Spica, or polares? Explain

Antares is more denser than Spica and Polaris.

The density of Antares is 1.563E-1, the density of Spica is 2.529E-2 and the density of Polaris is 2.778E-4. Antares is also known as the red supergiant. Antares is brighter than sun about ten thousand times but its brightness can't be experienced because it is 37 million times farther from our planet. Antares ranks 14th position in the list of brightest stars. From the above information about densities of three stars, Antares is the densest star as compared to other stars.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
