At the end of the school day, the teacher gives each student a compass. She explains that a compass is made of a small piece of metal called a needle. She also told students that the Earth has a magnetic force around it. She asked students to use what they've learned about electric and magnetic forces to explain why a compass always points north.
Which of the following is the best explanation of why a compass points north?
A.The needle of the compass is likely pulled towards the north because the needle and north area of the Earth are both positively charged, causing an attraction.
B.Since the Earth has a magnetic force, it must attract one end of the needle. The needle likely has an electric force that is affected by the magnetic force of the Earth.
C.Since the Earth has a magnetic force, it must attract one end of the needle. The needle is likely magnetic and has opposite charges on each end
.D.The Earth's magnetic force causes metals, like the needle of a compass, to point north because of the electric force in the needle. They likely repel each other.

Answer:

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. ... The spectrum of waves is divided into sections based on wavelength.

Explanation:

hope that helps!....

Answer:

When the frequency increases the wavelength decreases and vice versa. There are different sections: radio waves, micro waves, infrared rays, visible light, ultraviolet waves, x-rays, and gamma waves. You can see colors because of visible light.

Water Cycle

Explanation:

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
