Question

1. How do airplanes stay in the air?
2. Why is water wet?
3. Why don't birds get electrocuted when they land on an electric wire?

Answer 1

Explanation:

Birds do not get electrocuted when they land on wires because they do not represent a path to the ground. A bird on the wire doesn't give electricity anywhere to go except to go back to the wire, so it is easier for a current to continue on its way in the wire.

Answer 2

Answer:

Hey there !! Here is your answer to these fascinating questions

1. A plane's engines is designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky.

2. Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each.

3. When a bird is perched on a single wire, its two feet are at the same electrical potential, so the electrons in the wires have no motivation to travel through the bird's body. No moving electrons means no electric current.
