Answer:
You can use the mass-luminosity relation to find the star's lifetime in terms of just its initial mass. The lifetime = mass/luminosity × 1010 years is simply = (star's mass)/[(star's mass)p] × 1010 years = 1/(star's mass)p-1 × 1010 years. Remember that the star's mass is in solar masses.

The answer to this question is More elastic
A product usually become inelastic if that product does not have any subtitute to fulfill the same function.
In the long run, advancement in technologies will create a way cheaper method in producing energy (such as electric, nuclear, or solar) which will make natural gas become more elastic.
Answer:
The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent
Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
Answer:
because a bay consists of water, while a straight section on the coast wouldn't be much for miles. a bay is where these trading and fishing communities would b getting their sources from. this makes being located on or near a bay much more convenient than on a straight section of the coast
