You must make an aqueous solution that will be a good conductor of electricity. You can pick two substances to add to the water. Select the two substances that you could add to water to make it the strongest conductor possible

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
