Answer:
B. LZAQD
A. Younger than A but older than Q
Explanation:
To solve this problem, we simply apply the stratigraphic laws which are the law of superposition and principle of cross cutting.
- According to the law of superposition, in an undeformed sequence of strata, the oldest layer is always at the bottom and the youngest on top.
- In this case, we have a little disturbance but it did not affect much of the original bedding.
- So, the rock ages from L to Z to A to Q and D. L is the oldest and D is the youngest.
According to the principle of cross-cutting "features that cuts through a rock are younger than the layers they cut through". In this problem, the fault cuts through layers LZ and A which suggests that these layers are older than the faulting event. Layer Q is unaffected by the faulting so, the fault is older than the layer.
The answer for the question given above would be option C. The energy conversion that occurs when a solar panel uses <span>light to provide power to a house is radiant energy that is converted to electrical energy. Radiant energy is the same with light energy. Hope this answers your question. Have a great day!</span>
Answer:
Kinetic energy might transferred from one particle to another during an elastic collision, but i don't think that there is going to be any change in the total energy of the colliding particles. Because there are no forces of attraction or repulsion between gas particles .
Explanation:
Answer: Reproducible experiments help build confidence in the theory.
Explanation:
Reproducibility means repetition of an experiment by another scientist in order to check whether the result is same or not.
Further, this rechecked result is used by the scientist to carry out further research or experiments that can lead to the formation of a theory.
Thus, it can be concluded that reproducible experiments help build confidence in the theory.
Answer:
Explanation:
Atoms generally tend to achieve there octet configuration (i.e have there outermost shell completely filled) and become stable. They do this by participating in chemical bonding (majorly by transferring or sharing electrons). Atoms (of elements) that have very few electrons on there outermost shell (like the group 1 atoms; example is sodium) and atoms that have almost completely filled outermost shell (like the group 7 elements; example is fluorine) are highly reactive because it is easier to lose an electron to become stable and also easier to gain an electron to become stable. However, elements in group zero of the periodic table do not participate in bonding and resist chemical reactions because they have a completely filled outermost shell and are hence stable.
Since, the groups of the periodic table shows the number of electrons in the outermost shell of each member (of a particular group), the chemical properties of each group is usually almost similar.
