On may 26, 1934, a streamlined, stainless steel diesel train called the zephyr set the world’s nonstop long-distance speed record for trains. its run from denver to chicago took 13 hours, 4 minutes, 58 seconds, and was witnessed by more than a million people along the route. the total distance traveled was 1633.8 km. what was its average speed in km/h and m/s?

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
