Kirk wants to know if someone his height will go faster on a bike with a larger frame. what should he do next in order to follow the steps of the inquiry?
a. predict the effect of bike size on the speed of a rider his height.
b. design an experiment in which people his height ride bikes of various sizes.
c. observe riders his height riding bikes of various sizes.
d. time himself riding around a track on bikes belonging to several of his friends.

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
