Answer: Nail moving towards a magnet
Explanation: Since the iron nails and pins move towards the magnet, it means that the magnet exerts a force on them. The force exerted by a magnet is called magnetic force.
Answer:
The Earth:
- Is tilted 23 1/2° on its axis
.
-
Rotates from west to east
.
-
Bulges slightly at the equator
.
-
Revolves around the sun once every 365 1/4 days
.
Explanation:
The only option that is incorrect is the first one - The Earth has a circular orbit around the sun-. Although the Earth has an orbit around the sun, this one is not circular, it is elliptical, this is similar to an inclined oval, and the planet rotates in this orbit with an inclination on its axis of 23 1/2º.
As well as the shape of the orbit is not circular, the shape of the Earth is not equal in all its parts, it is wider in the equator in comparison with the North and South Poles.
It rotates from west to east in its axis, and it takes 365 1/4 days to complete a round in its orbital.
