Answer:

B) nearest to the sun

Explanation:

Density may be defined as the amount of matter a body contains. Mathematically, it is the ratio of the mass to the volume of space that it occupies. Density of an object will determine if the object sinks or it floats when the object is put into some liquid, such as water.  

In our solar system, the planets that are nearest to the sun are the terrestrial planets. They are composed of metals or mainly silicate rocks and they have a solid surface. They are Mercury, Venus, Earth and Mars. Thus they are densest planet as compared to other planets which are mainly composed of gases like Jupiter, Saturn, etc.

sladkih [1.3K]

<u>Answer</u>:

When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product ​is 92 and 234 respectively.

<u>Explanation</u>:

In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.

As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.

Fudgin [204]
I believe the answer is:
- A Chilean reporter shares live footage of an earthquake on the Web.

This is a perfect example of the power of the internet, where we have a country that is very far away and something happens in there and by using the internet you can visually see what is happening there in the exact same moment even though you may be on the total opposite side of the world.
