Question

1)How can you reduce friction?
2) what are non conventional sources of energy?​

Answer 1

Answer:

1) Methods for Reduction friction:

1) Make the surfaces little more smoother. ...

2) Lubrication is another way to make a surface smoother. ...

3) Make the object more streamlined. ...

4) Reduce the Normal force acting between the surfaces in contact. ...

5) Reduce the contact between the surfaces, so that less number of bonds will be formed.

2) Renewable energy sources, often known as non-conventional energy, are sources that are renewed by natural processes on a continual basis. Solar energy, wind energy, bio-energy (bio-fuels cultivated sustainably), hydropower, and other sustainable energy sources are some examples.

Answer 2
