Three cars, x, y, and z, begin accelerating from rest at the same time. x is more massive than y, and y is more massive than z. the net accelerating force exerted on each car is identical. after 30 seconds, which car has the most amount of momentum? a) they all have the same amount of momentum. b) car x c) car y d) car z e) cannot be determined based on the known information.

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.

Atruck driver is attempting to deliver some furniture. first, he travels 8 km east, and then he turns around and travels 3 km west. finally, he turns again and travels 13 km to his destination. what is the drivers distance

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
