A scientist has a container filled with carbon dioxide gas. The particles of this gas are far apart, moving quickly, and bouncing off the container walls. Then the particles slow down and collect at the bottom of the container, such that they are close together and vibrating in a rigid structure. What caused this change?
A.
Thermal energy was removed.
B.
The container was opened.
C.
Thermal energy was added.
D.
The particles settled over time.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
