A 4.00-m by 1.25-m rectangular loop is located in the x-y plane. A magnetic flux of 0.100 T is directed in +z direction. What is the magnetic flux through the loop? Give your answer to the nearest hundredth (0.01) Wb (weber). Do NOT included units in your answer. A single circular conducting loop is carrying a current of 8.5 A. The radius of the loop is 25.0 cm. Calculate the magnitude of the magnetic field at the center of the loop. Give your answer to the nearest tenth (0.1) microtesla. Do NOT use units in your answer Consider a simple magnifying glass with a focal length of 10.0 cm. Assuming a near point of 25.0 cm, what is the angular magnification of the magnifying glass if the object is at the focal point? A rubber rod is initially uncharged and rubbed with a piece of fur to transfer electrons from the fur to the rubber rod. Which (if any) of the following amounts of charge is NOT possible on the rubber rod? Assume the charge on a single electron is -1.6 x 10-19 -6.4 x 10-19 C 0 -2.4 x 10-18 -2.4 x 10-19 -3.2 x 10-19 C All of these charges are possible.
