Cara is explaining to her sister how the solar system formed. Which description would she use to explain the solar nebula
Alexandra [31]

Answer:

The correct answer is A. a rotating cloud of dust and gas.

Explanation:

Nebulae are regions of the interstellar medium (clouds) made up of gases (mainly hydrogen and helium) and dust. In other words, nebulae are concentrations of gas in which we find hydrogen, helium and stardust in greater quantities. They are structures that are actually very important for the universe, this because inside it is the place where stars are born, which arise due to the condensation and aggregation of matter. The nebular theory states that the Solar System reached the form current from a solar nebula (a gas cloud), more than 4.5 billion years ago. The large cloud of molecular gas was affected by a certain phenomenon that would have taken place in the vicinity. Like the explosion of a supernova or the passage of a star that would produce a strong gravitational impact. The result of this event made the matter agglomerate in different places. The high concentration of matter caused the nebula to collapse. Becoming a protostar, (bodies whose characteristic is to be surrounded by clouds and contain preplanetary matter inside), that is, gaseous matter in the outermost part and solid inward. At the core of this structure, the temperature is so dominant that nuclear reactions take place to compensate for the gravitational force. This leads to a hydrostatic equilibrium and the formation of a fundamental star: the Sun. The rest of the mass flattened, forming a protoplanetary disk where the protoplanets were being formed, which would evolve to become the current planets, their satellites and the others bodies of the solar system.

Which of the following initiatives help harvest renewable energy in some TCS offices
Marianna [84]

The initiative (technology) which help harvest renewable energy in some TCS offices is: Solar water heaters.

TCS is an acronym for Tata Consultancy Services and it is a multinational IT services, consulting and business solutions company that was established on the 1st of April, 1968 in Mumbai, India. Also, TCS has a large network of initiative (technology), innovation and delivery centers across the world.

In 2013, TCS was deeply invested in harnessing renewable energy to generate electrical energy and reducing the emission of carbon, especially by developing solar energy. Thus, solar product solutions such as solar water heaters and lighting systems were installed in some of its offices because they were economically viable and would help meet their energy needs.

In conclusion, solar water heaters was the initiative (technology) that helped harvest renewable energy in some TCS offices.
