Suppose you have two magnets. magnet a doesn't have its poles labeled, but magnet b does have a clearly labeled north and south pole. if these two are brought into contact with one another, which of the following could you expect?

a. the side of magnet a that's attracted to magnet b's north pole must be magnet a's north pole.
b. the side of magnet a that's repelled by magnet b's south pole must be magnet a's north pole.
c. the side of magnet a that's attracted to magnet b's south pole must be magnet a's north pole.
d. the side of magnet a that's repelled by magnet b's north pole must be magnet a's south pole

Waves that cause the most damage during an earthquake are a. surface waves c. s waves b. p waves d. ocean waves

Select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air

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
