Answer:
The correct options are;
1) The chemical composition of our solar system matches the chemical composition of the Milky Way
2) Nearly all atoms of elements heavier than helium were produced through nuclear fusion in stellar interiors and through reactions that occur during explosions that massive stars undergo at the ends of their lives or during mergers of stellar remnants called neutron stars
3) Some of the oldest galaxies are about 13.2 billion years old
4) Nucleosynthesis is a process through which the atoms of various elements are produced
5) You re mainly made of hydrogen
Explanation:
1) There are dependencies between chemical composition of stars and planets and the same distribution of chemicals we have in our Solar system have been observed to be present in varying resemblance through out the Milky Way
2) The formation of heavier elements are believed to have been formed by astrophysical fusion processes
3) The oldest known object (and hence the galaxy where the star resides), is from a distant star known as GRB 090423 which is about 13 billion years old
4) New atomic nuclear are created by the process of protons and neutrons by the process of nucleosynthesis
5) 62%of the atoms in the body are hydrogen atoms.
Answer:
Explanation:
The human body utilizes the effect evaporation for cooling. Hence the water on the body surface make the skin to experience chilly as the wind blows to evaporate it. As the latent heat of vaporization is extracted from the body, it is cooler in the process. This is the same reason why perspiration cools the body as the sweat evaporate from the surface of the skin.
Answer:
The more energy a sound has the louder we perceive it
Explanation:
To measure volume we use the unit of decibels – abbreviated to dB. The lowest perceivable volume, meaning the quietest sound humans can hear, is 0 decibels. ... Thus, 60 dB are perceived as twice as loud as 50 dB
