Answer:
Once a well has reached the water table, it will not run dry true or false? -earth science
Explanation: IT IS FALSE!!! HAVE A GREAT DAY
The mechanical energy of the system at any point in time can be in the form of kinetic energy, potential energy, and elastic energy. These all are interconvertible, hence mechanical energy is conserved.
The term mechanical energy accounts for the total energy by the virtue of position as well as the motion of an object.
When an object is dropped from a certain height, then the mechanical energy of the object at any instant is given as the sum of kinetic energy and potential energy. The expression is given as,
ME = KE + PE
But at some point in time, the potential energy can be in the form of elastic energy as well. This energy is known as spring potential energy. Hence, the mechanical energy is conserved in a system at any point considering the forms like kinetic energy, potential energy, and elastic energy.
Thus, we can conclude that the mechanical energy of the system at any point in time can be in the form of kinetic energy, potential energy, and elastic energy. These all are interconvertible, hence mechanical energy is conserved.

Answer:
High crater density is associated with older surfaces.
Explanation:
The total amount of DNA is compared between two species.
The percent of carbon in DNA is compared between parent and offspring.< The total mass of DNA is compared between parent and offspring.
Answer:
The correct answer is a = The number of mutations in DNA is compared between two species.
Explanation:
Hello ! Let's solve this!
The molecular clock is a technique to see the divergence between two species. In other words, to see DNA mutations.
The correct answer is a = The number of mutations in DNA is compared between two species.
Star 2 is 75 miles away from Star 3.
Star 2 is 63 kilometers away from Star 3.
Star 1 is 12 light years away from Star 3.
Star 1 is 138 light years away from Star 3.
I just took th test it is letter D for sure!
Answer:
B. The surface of the Earth heats the air that contacts it.
Explanation:
Conduction is a mode of heat transfer in which energy is transferred from a hot molecule to the neighboring molecules due to contact. Thus, heat energy is transferred from one molecule to another in the process.
Therefore, the air that comes in contact with the surface of the earth heats up by conduction. Since the surface of the earth is heated up due to the radiation from the Sun.
Answer: B.
Explanation: I took the test. Also, after my diagnostic I just wanted to see if my answers were correct lol.
