Ques:Answer the following question given this paragraph: Most of the stars pictured in this view of the night sky are hundreds of light years from Earth. A light year is the distance that light can travel in a year, or about 6 trillion (6,000,000,000,000) miles. As this example shows, quantities in science may be very large. Many other quantities in science are very small. Both very large and very small numbers have many zeroes, so they are hard to read and write without making mistakes. That's where scientific notation comes in. Q: The distance that light can travel in a year is known as what? Choices: - earth year - beam year - solar year - light year A:

Ans:light year
