Jack Frost pulls on a rope of a sled giving his friend Cindy Lou Who a ride across an icy pond surface (assume no friction). He pulls the rope with a force of 40 N at some angle above
the horizontal moving the sled a distance of 8.31 meters. He does 247 Joules of work on the
sled. What angle does the rope make with the horizontal?

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.
