The difference between protons and neutrons are that one has a positive charge and one has a neutral charge. The similarities between the two is that they both make up an atom. The Electrons in an atom are in orbit of the cell inside the Electron cloud and is kept in the cloud by electromagnetic force.
I think its false because gas exchange can happen in blood also
Answer : The The correct option is, If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.
Explanation :
- Elastic collision : It is defined as in which there is no loss of kinetic energy in the collision.
- Inelastic collision : It is defined as in which there is a loss of kinetic energy in the collision and this energy changed to another form of energy.
If the collision involves bouncing, it is inelastic because kinetic energy is not conserved.
If the collision involves sticking together, it is inelastic because kinetic energy is not conserved, it is changes to potential energy.
The answer is (D)
Composting helps in manufacturing of manure which is very very healthy for the plants.
Reusing , reusing plastic bags can be helpful for the environment
Recycling , can be used to convert plastic into other useful substance , which is an advantage for the environment.
