Answer/ Explanation:
Question #1:
The table shows the interactions between different objects that were rubbed together. The objects include a Teflon rod, fur, glass rod, silk, plastic bottle, and more. The interactions are classified as either attraction or repulsion. The charge of the rubbed object is indicated as either positive or negative.
Question #2:
To complete this task, you need to take a snapshot of the completed table. This can be done by capturing a picture or saving a copy of the table for later reference.
Question #3:
Upon reviewing the data tables, a pattern can be observed in the charges of two objects after they were rubbed together. The pattern is that objects with different materials, such as Teflon rod and fur, glass rod and silk, or plastic bottle and silk, tend to attract each other. Conversely, objects with the same material, such as Teflon rod and fur, or glass rod and silk, tend to repel each other.
Question #4:
In the previous investigation, it was learned that all materials are made of atoms, which consist of positively charged protons and negatively charged electrons. If an object is neutral, it can be concluded that the charge of the atoms making up that object is balanced, meaning there are an equal number of protons and electrons. This balance of positive and negative charges results in a neutral overall charge for the object.
