A student buries an ice cube in a pan of dirt and observes the dirt as the ice cube melts. This activity is a model of the formation of a kettle.
<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.

The answer is B. Buddhism. This is because Buddhism, which started in India, came to Japan and became a major religion. The local Japanese people already had their own religion (which focused on nature's spirits and the spirits of their ancestors), so they took some of the beliefs of Buddhism and mixed it with their own cultural beliefs. I hope this helps!
