Studies of sedimentary rocks and fossils have helped scientists understand the history of Earth. the geologic time is organized on the geologic time scale as eras and then smaller periods based on geologic and biologic events that occurred during those times, therefore the correct answer is B .
Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.
As given in the problem statement Studies of sedimentary rocks and fossils have helped scientists understand the history of Earth .
Studies of fossils and sedimentary rocks have aided in the understanding of Earth's history. The correct response is B since the geologic time is divided into eras and then smaller periods depending on the geology and biological events that took place during those times .

The answer is B) eras and then smaller periods based on geologic and biologic events that occurred during those times. I took this test :)
Answer:
2r
Explanation:
As we know that
The displacement is the total distance measured between the initial or start and final or destination point
If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point
We attached the diagram for better understanding
As per the diagram.
The displacement after half-circle is
AB = OA + OB
= r + r
= 2r
upward
B.
toward the right
C.
toward the left
D.
downward
Answer:
1/4
Explanation:
The period of a simple pendulum is:
T = 2π √(L/g)
At half the period:
T/2
= π √(L/g)
= 2π √(L/(4g))
= 2π √((L/4)/g)
So the length would have to be shortened by a factor of 1/4.

Answer: Increase internal energy and work done by the system
Explanation: According to the first law of thermodynamics conservation of energy, when heat is added to the system then the system gain or loss of energy.
So, when we add heat to a system then increases internal energy and external work done by the system.
temperature rises ? specific heat capacity etc ...
