Answer:

wind energy

Explanation:

Wind energy can be defined as a form of a solar energy. It is generated by the immense force of the wind that blows in an area. Wind energy is a useful energy and is mostly used to generate electricity. It is clean source of energy.

In the context, trash can lid is being blown away by the wind energy and it is seen moving across the yard. The energy of the wind forces the lid of the trash can to move from one place to another against friction. Thus, wind energy caused the trash can lid to move across the yard as seen by a student.

22. State any three features of the electroscope.​
MatroZZZ [7]
-1- was created in the 1600 by william gilbert
-2-When the charge is positive, electrons in the metal of the electroscope are attracted to the charge and move upward out of the leaves. This results in the leaves to have a temporary positive charge and because like charges repel, the leaves separate. When the charge is removed, the electrons return to their original positions and the leaves relax
3-

An electroscope is made up of a metal detector knob on top which is connected to a pair of metal leaves hanging from the bottom of the connecting rod. When no charge is present the metals leaves hang loosely downward. But, when an object with a charge is brought near an electroscope, one of the two things can happen.
