Answer 1

Explanation:

1- The following steps should be taken for the conservation of forests:

Regulated and Planned Cutting of Trees:

Control over Forest Fire:

Reforestation and Afforestation:

Check over Forest Clearance for Agricultural and Flabitation Purposes:

Protection of Forest:

Proper Utilisation of Forest Products and Forests:

2- Newton's Optical disc is a very popular experiment done by Sir Isaac Newton to demonstrate the optical mixing also called the temporal optical mixing or the Additive averaging mixing. Newton disc contains the transparent films of different colours like violet, indigo, blue, green, yellow, orange and red.

3- Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
