The answer is 2 because you have to divide these numbers.<span />
Answer:
They have properties of both metals and nonmetals
Explanation:
- Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
- Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
- Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
- Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
- Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.
Explanation:
The scale is pushing back up against her feet with the same amount of force but in negative direction.
This can be explain using Newton's third law of motion which states that "action and reaction are equal and opposite".
As the girl weight pulls down on the scale in a positive way with a force of 42N, the scale pulls back with an equal amount of force upward in another direction.
The net force here is zero this is why the scale is not damaged by her weight.

Answer:
The correct option es interphase
Explanation:
The interface is a stage of the cell division where a lot of energy is demanded, and it is the longest of the entire cycle.
This is because it is here where the duplication of the genetic load is generated, that is, of the chromosomes.
The chromosomes reach the cell poles and this is how a contraction begins to appear in the middle of the cell, it is essential to clarify that the interface not only requires energy but also occupies 95% of the cell division.
