Answer:
Wind is the primary renewable resource used for electric power generation in the state. In 2019, wind provided 97% of the state's renewable energy generation, and Illinois was sixth in the nation in utility-scale (1 megawatt or greater) wind capacity, with about 5,200 megawatts online.

Perform a simple test of the material in the pan to assess whether it is real gold. Raw gold appears brassy yellow and bright. If you think it is gold, place your hand between it and the sun to create shade over the gold. If it still appears bright in the pan, chances are that it is real gold.

Answer:
On removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge due to deficiency of electrons.
Explanation:
When a glass rod is rubbed against a nylon then the electrons from the surface of the glass rod get transferred to the nylon piece and as a result the glass rod attains positive electrostatic charge.
When this positively charged rod is brought close to the knob of an electroscope then the electrons from that metallic of the electroscope feel attraction and move toward the glass rod get concentrated on the knob.
- In this situation when any of our body part comes in direct contact to the knob these static concentrated charges get a path to flow from high concentration to a lower concentration under the influence of the electrostatic force of the rod.
- So these charges flow into our body from the knob.
- Our body acts as a reservoir for the charges on the metallic knob.
- Now after the electrons form the knob are transferred to the person's body the electroscope becomes electron deficient and hence positively charged.
- So now, on removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge.
The base unit of time in the metric and SI system is the second.
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
