Explanation:
Cuando una roca se somete a un esfuerzo creciente, pasa por 3 etapas sucesivas de deformación. Deformación elástica: en la que la deformación es reversible. Deformación dúctil: en la que la deformación es irreversible. Fractura: tensión irreversible en la que el material se rompe
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.

Dichotomous keys can only be used to classify organisms based on their observable traits.
Dichotomous keys can only be used if the name of the species is unknown.
Dichotomous keys can only be used if the name of the species is known.
The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.
What is a Dichotomous key?A dichotomous key might be considered a significantly useful tool to classify organisms.
The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Each time you choose an option, it leads you to the following description, which gets more specific each time.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies.
You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

b. Impossible to calculate since the speed wasn't constant.
C. 0.9420/s north
d. 56.67 m/s north
e. 1.34 m/s north
f. 0.56 m/s north
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=0.9420m/s[/tex]
Answer:
0.9420m/s north
Explanation:
Given,
Displacement (Total) = 6800 metres(m)
Time = 2 hours
We need to convert hours to seconds.
2 hours = 7200 seconds
We know,
[tex]\sf\longmapsto \: Average \: velocity = \frac{Total \: Displacement}{Total \: time} [/tex]
Let's start solving!
[tex]\sf\longmapsto \: Average \: velocity = \frac{6800 \: metres}{7200 \: seconds} [/tex]
[tex]\sf\longmapsto \: average \: velocity = 0.9420\: m/s[/tex]

HELP PLEASE!!!explain how Earth is heated through conduction
As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.
It must be known that conduction happens mostly near the earth's surface.
Answer:
Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

Using a virtual model, I compared low and high velocity streams or rivers, low and high gradient streams or rivers, and low and high volume streams or rivers. I found that higher velocity streams or rivers can cause more erosion, as do higher gradient and higher volume streams or rivers. Not only did these factors move more small sediment, they also moved larger pieces of sediment."

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Simply when layers of eroded material pile to create new landforms. For example, coastal deposition is how beaches are formed.
The geological process of deposition involves the addition of sediments, soil, and rocks to a landform or landmass. when eroded debris is piled up in layers to produce new landforms.
What is deposition?A deposition is testimony made under oath and taken down in writing by an authorized officer of the court, typically in an out-of-court setting and before trial.
Depositions are usually taken from key witnesses, but can also involve the plaintiff or defendant, to give the involved parties a fair preview of all the evidence.
The individual making the deposition is known as the deponent and false statements can carry civil and criminal penalties.

What was the universe immediately before the Big Bang occurred?
a black hole
a singularity
a super spiral galaxy
a mass of antimatter
the answer is a black hole
The universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.
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.
