Magnets will always... 5 points
Attract to aluminum and other non-metals
Repel each other when their poles are opposite (i. e. a North and South pole)
Attract when opposite poles (North/South poles) are next to each other

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Why do different substances have diffrent properties

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
