<span>A homogeneous mixture would be
something like a solution, where you can't see the different parts of the
mixture. It's like how in salt water, you see one uniform substance (the water).
A heterogeneous mixture is the opposite; you can see the different parts
that make it up. An example would be soil, where you can see rocks and leaves
and the parts that make it up, etc</span>

Answer:
The K.E is maximum when the child is at the vertical position and the P.E is maximum at the extreme deviated position from the vertical.
Explanation:
- A child is swinging on swing up and down has both kinetic and potential energy.
- The total mechanical energy of the system is conserved throughout the system. At any instant the total mechanical energy is given by,
E = K.E + P.E
- The K.E is maximum when the child is at the vertical position.
- The P.E is maximum at the extreme deviated position from the vertical.
- And when K.E is maximum P.E becomes minimum and vice versa as per the law of conservation of energy.
