Answer:
More info given below.
Explanation:
This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
Answer:
A) Education Websites
Explanation:
Because generally websites, are signed by an author that will also state sources to their information for verifcation.
<span>By using superposition and cross cutting relationships, geologists can determine relative ages of rocks. This means they can determine which rocks are older and which are younger, but not the exact ages of the rocks. </span>
Protons have a positive charge
Neutrons have a neutral charge
Electrons have a negative charge
Answer:
In the last step of the scientific process when they compare their results.
Explanation:
The scientific process can be described of the following steps in order:
Starting with the observation, finding a point that asks a question which will be investigated, constructing a hypothesis that can be tested, testing the hypothesis and lastly comparing the results and starting over.
The example given in the question has a question to investigate, the students have a hypothesis. They test it and find out that the water sample can hold 20 amoeba which does not match their predictions. The students will check if their results match their predictions in the last step of the process when they compare their results with their hypothesis.
I hope this answer helps.
