Two cars travel in the same direction along a straight highway, one at a constant speed of 51 mi/h and the other at 76 mi/h. assuming they start at the same point, how much sooner does the faster car arrive at a destination 14 mi away?
how far must the faster car travel before it
has a 12 min lead on the slower car?
answer in units of mi.

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.

A10-kg piece of aluminum sits at the bottom of a lake, right next to a 10-kg piece of lead, which is much denser than aluminum. which one has the greater buoyant force on it? explain. b - the aluminum a) both have the same buoyant force. b) the aluminum c) the lead d) it cannot be determined without knowing their volumes.
