Explanation:
Since the comb has a net charge, it attracts the paper, which has a net charge equal to zero. When the paper touches the comb, an electrical interaction is established between the charge of the comb and the neutral paper, because of this, the paper now has a net charge with the same sign of the comb and they repel.
Answer:
Using the Fundamental Equation of Wave, we have:
Explanation:
Using a stronger magnet; Increasing the current in the magnet; Decreasing the distance between the magnets
When you want to jump UP, you push DOWN on the Earth. Then, because of Newton's 3rd law, the Earth immediately pushes UP on you, and this equal, opposite REaction is the force that lifts you up.
