To separate a mixture of salt and water, you can try first by using filter paper hen with the extra water part set it out to the window so that the salt water evaporates and only the salt is remaining.
Acceleration represents the change in velocity.
Light, being both a wave and a particle, displays many properties similar to both of them. Light, like waves, travels at different speeds through mediums because they provide any variable amount of resistance. Even air resists light to a degree, and light speed through air is slower than light speed in a vacuum.
Static electricity is electricity produced locally that does not flow. It is produced by electrons being rubbed off one object and collecting on another. It cannot flow through a wire like the electricity in your home.
Example:
1) Rub a balloon on your hair and it will stick to the wall. The balloon rubs electrons off your hair and picks up a negative charge. Your hair, in turn, is left with a positive charge. You may even notice your hair has "static" and is standing out from your head.
2) Comb your hair with a plastic comb then use it to pick up small pieces of paper. The comb picks up electrons from your hair and becomes negatively charged. It uses this charge to attract the pieces of paper.
3) Rub your slippered feet on the carpet and then touch something metal like a door knob. The "shock" you feel is static electricity. You pick up electrons from the carpet and discharge them on to the door knob.
