The gymnast swings from one bar to the other bar several times Describe how the gravitational potential energy store and the kinetic energy store of the gymnast change as she moves between the bars ​

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

Give an example in which the electrical energy changes to light energy
