HURRY UP !!!

D. A battery provides electrical energy to power a phone.

Explanation:

Examples of current electricity are starting a car, turning on a light, cooking on an electric stove, watching TV, shaving with an electric razor, playing video games, using a phone, charging a cell phone and more.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
