5.4-2 An infinite line of charge having uniform density +8 mC/m exists along the z-axis. In addition, a infinite sheet of charge having uniform charge density +12 mC/m2 lies in the z = 0 plane. If the permittivity of the medium is twice that of free space, then what is the electric field intensity in the region z > 0? Express your answer in cylindrical coordinates.

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Apatient has a history of poor nutrition. he has skin rashes, bleeding gums, and a cut that hasn’t healed in a long time. what vitamin deficiency most likely caused this symptom?
