Egbert is in a rowboat four miles from the nearest point on egbert a straight shoreline. he wishes to reach a house 12 miles farther down the shore. if egbert can row at a rate of 3 mi/hr and walk at a rate of 4 mi/hr, find the least amount of time required to reach the house. how far from the house should he land the rowboat? justify your answer.

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
