A0.358 kg particle slides around a horizontal track. the track has a smooth, vertical outer wall forming a circle with a radius of 1.66 m. the particle is given an initial speed of 8.19 m/s. after one revolution, its speed has dropped to 6.29 m/s because of friction with the rough floor of the track. calculate the energy loss due to friction in one revolution.

Which statement best explains why an object weight less on mercury than it does on earth

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

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.
