Aman with a mass of 80.0 kg is out fishing with his daughter, who has a mass of 25.0 kg. they are initially sitting at opposite ends of their 3.0-m boat, which has a mass of 60.0 kg and is at rest in the middle of a calm lake. the man and the daughter then carefully trade places. we will neglect any resistive forces between the boat and the water. how far has the boat moved, once the man and his daughter have finished trading places?

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
