Answer:
Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface tension and, of course, gravity.
Explanation:
:}
When the cohesive forces between the liquid molecules are greater than the adhesion to the walls, capillary action results. Surface tension and, of course, gravity set a limit on how high capillary action may raise water in a uniform circular tube (see image to the right).
What is Capillary action in plants?Water is transported to the remainder of the plant by capillary action up the stems and roots. Through the plant, water is transported through capillary action.
Water (the liquid) molecules are drawn to the molecules of the stem's interior (the solid).
The purpose of this attraction is to help lift the water out of the ground and distribute it throughout the plant.
When the forces holding a liquid together—cohesion and surface tension—and the forces drawing that liquid to another surface—adhesion—are stronger than the force of gravity, capillary action takes place.
Therefore, through cohesive forces and surface tension, water moves up a vessel against gravity.

What is the Big bang?The big bang may be defined as the cosmic explosion that significantly marked the initiation of the universe according to the big bang theory. The origin of the universe is explained by the Big Bang theory.
At initial, the whole universe appeared like a black hole where no life is present. It was all the dark around each and every corner. The universe was an infinite stretch of ultrahot, dense material and everything consisted of empty space.
Before the big bang, the universe was almost infinitely small, dark, and a size less than a trillionth of a second. It was a period of inflation which is followed by a more catastrophic event which was violent, and known as the period of expansion.
Therefore, the universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.

Explanation:
is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?
Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger
Answer:
c-risk trigger
Explanation:
The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA. The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.

Explain how scientists use geologic time to determine the age of landforms.
Answer:
scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.
Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:
Radiation Measurement
Stratigraphic Superposition
The Fossil Record
From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.

Explanation:
One person pulls on a rope with a force of 400 N to the right. Another
person pulls on the opposite end with a force of 600 N to the left. What is
the net force?
Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.
What is Net force?Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.
If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.
Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.
As a result of these forces, the net force applied on the rope can be calculated by:
Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction
Net force = 600N (force applied to the left) - 400N (force applied to the right)
Net force = 200 N and the direction will be left as the magnitude is more in left direction than right
Therefore, the correct option is A.
