A compass needle normally points toward Earth’s magnetic pole, which is near the North Pole. Which best explains why the needle moves away from the pole when it comes close to a current-carrying wire?-Current within the wire weakens the magnetic force of the pole.
-Magnetism surrounding the wire weakens the magnetic force of the pole.
-Magnetism surrounding the wire draws the needle toward the wire.

Answers

Answer

-Magnetism surrounding the wire draws the needle toward the wire.

Explanation
When a compass needle is placed near a conductor carrying current, it deflects to one side.
This happens because the magnetic field due to the needle interact with electric fields around the conductor carrying carrying current resulting to a force that makes the needle to deflet.
The best answer that suits the question asked is -Magnetism surrounding the wire draws the needle toward the wire.

What is the distance an object would be from Earth if its parallax were one arcsecond?a. a parsec
b. a light-year
c. an arcminute
d. an angular diameter

Answers

The correct answer is (a.) a parsec. A parsec is a distance an object would be from Earth if its parallax were one arcsecond. This unit of measurement is usually used in astronomy which makes it easier for astronomers to calculate or measure in space accurately.

What evidence did Alfred Wegener use to support his theory of continental drift?

Answers

Explanation:

Alfred Wegener was a meteorologist and geologist. He was inspired by a map of continents to start the journey of explaining Earth's geological history. He gave the theory of continental drift which says that the continents of Earth have moved relative to each other over time. He used following evidences to support his theory:

1. The facing side of South America's and Africa's shoreline interlocks perfectly. Which implies they must have been joined together in history.

2. Fossil of same type of reptiles found on different continents separated by huge oceans.

3. Matching the rock pieces on either side of the Atlantic oceans.

Answer: The correct answer is: coastline fits between different continents, similar rocks and fossils on different continents
