(a) calculate the amplitude (largest magnitude) and direction of the magnetic field produced by the two power lines at the base of the tower, when a current of 2 ✕ 104 a in the left power line is headed out of the page, and a current of 2 ✕ 104 a in the right power line is headed into the page. magnitude t direction

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Which of the following are appropriate acceleration units?

If frequency goes up, what happens to wavelength? does it get shorter or longer?
