A0.274 kg block is pushed up a frictionless ramp inclined at angle of 32° above the horizon. the push force is a constant 2.55 n and is parallel to the ramp. what is the speed of the block after it travels a distance d = 0.71 m if the block starts from rest? use work and energy.

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.
