A sugar glider jumps from a tree. At the top of the the tree, her Potential energy is 684.0J. Ignore air resistance. When she has
fallen part of the way to the ground, her kinetic energy is 10.04 J.
What is her new PE?

Which statement correctly describes a step-up transformer? a. it increases the amount of electric energy available. b. it increases the voltage of an electric current. c. it changes direct current into alternating current. d. it has more loops of wire in its primary coil.

**urgent** roberto plans to use two transformers to reduce a voltage of 120 v to 4 v. he uses a transformer that has 300 coils in the primary winding and 50 coils in the secondary winding. he has four other transformers, as listed in the table. which transformer should roberto use to have an ending voltage of 4 v? a- w b-xc- yd- z

Which best describes the difference between internal and thermal energy?
