A lady moves a suitcase of mass 22.3 kg with frictionless wheels across a horizontal floor by pulling on a cord attached to the suitcase making an angle of 0 = 46.4 degrees to the horizontal, as shown in the diagram. If the lady pulls the cord with a force of 15.1 N, what is the magnitude of the acceleration of the suitcase, in units of m/s2

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
