Why do scientists use the international system of units (si)

Answer:

Establishing laws that decrease cooperative behaviour.

Explanation:

A social trap refers to short term benefits, but long terms loss in a certain social group, that's why is called trap. One good example of social trap could be overexploitation of resources. Our societies is inside this social trap, which help to develop the economy, but with a long term ecology costs, because it degrades complete ecosystems.

So, in this case, the only answer that don't contribute to reduce this social problem, it's "establishing laws that decrease cooperative behaviour", because the lack of cooperativeness is one way to ensure the perpetuation and development of social traps.

All other options, actually contributes to reduce this social phenomenon. Modelling altruistic behaviours, education, and regulations on behaviour which could impact collectives, all of these are positive decisions that improve our social intelligence, and could ensure the reduce of social traps.

Answer:

Transformer

Explanation:

Transformers can increase (step up), or it can decrease (step down) voltage.

Final answer:

The most relevant information to determine whether an organism is unicellular or multicellular is the number of cell types in the organism, as multicellular organisms tend to have many different cell types, while unicellular organisms have just one.

Explanation:

If a scientist is attempting to determine if an organism is unicellular or multicellular, the most helpful information would be to understand how many types of cells are in the organism (option C). This is because multicellular organisms generally have many different types of cells carrying out specialised functions (e.g., nerve cells, blood cells, muscle cells), whereas unicellular organisms only have one cell type that fulfils all life functions.

For example, a human (a multicellular organism) has several different types of cells such as skin cells, kidney cells, and heart cells. On the other hand, an amoeba (a unicellular organism) has a single cell handling all functions necessary for survival.

Answer:

A freely falling object have fallen from a position of rest when its instantaneous speed is 10 m/s, it will travel 5.102 meter.

Explanation:

 We have equation of motion, , where u is the initial velocity, u is the final velocity, s is the displacement and a is the acceleration.

 In this case we have final velocity = 10 m/s, initial velocity = 0 m/s, and acceleration = 9.8 .

Substituting

A freely falling object have fallen from a position of rest when its instantaneous speed is 10 m/s, it will travel 5.102 meter.

Final answer:

When an object, starting from rest, achieves an instantaneous speed of 10 m/s while freely falling under gravity, it will have fallen approximately 5.10 meters.

Explanation:

Using the physics concept of motion under gravity, where the first equation of motion can apply (v = u + gt), your question involves finding the displacement of a freely falling object starting from rest until it reaches a speed of 10 m/s.

In this case, initial velocity (u) is zero because the object was at rest, the final velocity (v) is 10 m/s, and g is the acceleration due to gravity which is approximately 9.81 m/s².

We could rearrange the equation to find time: t = v/g = 10 / 9.81 ≈ 1.02 s. Then, we employ the second equation of motion to find the distance fallen, s = ut + 0.5gt². Since u=0, the formula simplifies to s = 0.5gt². Substituting g = 9.81 m/s² and t = 1.02 s into the equation yields s = 0.5 * 9.81 * (1.02)² ≈ 5.10 m.

Therefore, a freely falling object will have fallen approximately 5.10 meters when its instantaneous speed is 10 m/s.

Answer : The correct option is, (D) They have the same number of electrons in their outermost shells.

Explanation :

Periods : A row in the periodic table is known as periods.

The common features about the elements of a period are :

Each periods has elements with the same number of electron shells or energy levels or shell.

They transition from metal to noble gas that means they move from metal to non-metal and then non-metal to noble gas.

Groups : A column in the periodic table is known as groups.

The common features about the atoms of elements in a same group are :

Each groups has elements with the same number of valance electrons or have same of electrons in their outermost shells.

The elements in the same group have similar chemical properties.

The elements in the same group have similar physical properties.

Hence, the correct option is, (D) They have the same number of electrons in their outermost shells.
