Consider a straight wire 200 meters long, which is uniformly charged with 103 esu per centimeter of length, running parallel to the earth at a height of 5 meters. What is the field strength at the surface of the earth, immediately below the wire

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?
