A student claims that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the student's claim?
Responses
If the distance between two objects decreases, the gravitational force between the objects will not change

If the distance between two objects increases, the gravitational force between the objects will decrease.
If the distance between two objects increases, the gravitational force between the objects will decrease.
If the distance between two objects decreases, the gravitational force between the objects will disappear.
If the distance between two objects decreases, the gravitational force between the objects will disappear.

A student makes the claim that the space around a charged particle will exert a force on any other charged particle that is placed within this space. If an object is placed between two charged metal plates, one plate that is positively charged and one plate that is negatively charged, which argument BEST supports the student's claim?
Responses
An object with a negative charge will remain stationary between the plates.
An object with a negative charge will remain stationary between the plates.
A neutrally-charged object will move toward the negative plate.
A neutrally-charged object will move toward the negative plate.
A neutrally-charged object will move toward the positive plate.
A neutrally-charged object will move toward the positive plate.
An object with a positive charge will move toward the negative plate.
A neutrally-charged object will move toward the positive plate.
Which drawing below represents the electric field surrounding two objects that have EQUAL magnitude charges of the SAME polarity?
Responses
Unfortunately, as an AI language model, I cannot produce images, but I can describe them.
The correct answer would be two diagrams that show electric field lines that emanate from both charged objects and that are evenly spaced and parallel. Therefore, the correct option would be two diagrams that are identical to each other.
The image shows a large bar magnet with the poles labeled.
How would the poles of the magnet change if it were divided into four equal parts?
Responses
Unfortunately, as an AI language model, I cannot provide any image. However, I can describe how the poles would change if the magnet is divided into four equal parts.
If the magnet were divided into four equal parts, each part would have its own north and south pole. The original north pole of the magnet would become two north poles, and the original south pole would also become two south poles. Therefore, the magnet would have four poles instead of two, with each smaller section having its own pair of north and south poles.
