The fictional rocket ship adventure is measured to be 65m long by the ship's captain inside the rocket. when the rocket moves past a space dock at 0.5c. as rocket ship adventure passes by the space dock, the ship's captain flashes a flashlight at 1.40-s intervals as measured by space-dock personnel.
how often does the flashlight flash relative to the captain?

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
