Scientific Notation and Light Speed

This tutorial covers solving word problems using scientific notation. It includes calculating the distance from Earth to the Moon, comparing the diameters of Earth and a golf ball, and determining the area of the Atlantic Ocean. The tutorial emphasizes the use of scientific notation for multiplication, division, and subtraction, providing step-by-step examples and explanations.

What is the approximate speed of light in miles per second?

• 100,000 miles per second

• 150,000 miles per second

• 200,000 miles per second

• 186,000 miles per second

How long does it take for light to travel from Earth to the Moon?

• 0.75 seconds

• 3 seconds

• 1.25 seconds

• 2.5 seconds

What is the first step in expressing the distance from Earth to the Moon in scientific notation?

• Multiply the speed of light by the travel time

• Convert the speed of light to kilometers

• Add the speed of light to the travel time

• Divide the speed of light by the travel time

What is the scientific notation for 186,000 miles?

• 1.86 x 10^5

• 186 x 10^3

• 18.6 x 10^4

• 1.86 x 10^6

How do you calculate the distance from Earth to the Moon using scientific notation?

• Multiply 1.86 by 1.25 and keep 10^5

• Add 1.86 to 1.25 and keep 10^5

• Subtract 1.25 from 1.86 and keep 10^5

• Divide 1.86 by 1.25 and keep 10^5

What is the diameter of a golf ball in scientific notation?

• 4.27 x 10^3 millimeters

• 4.27 x 10^2 millimeters

• 4.27 x 10^1 millimeters

• 4.27 x 10^0 millimeters

How do you determine how many times greater Earth's diameter is than a golf ball's diameter?

• Add Earth's diameter to the golf ball's diameter

• Subtract the golf ball's diameter from Earth's diameter

• Divide Earth's diameter by the golf ball's diameter

• Multiply Earth's diameter by the golf ball's diameter

What is the first step in dividing two values in scientific notation?

• Subtract the exponents

• Add the coefficients

• Multiply the exponents

• Divide the coefficients

What is the approximate result of dividing 1.27 by 4.27?

• 0.5

• 0.9

• 0.3

• 0.7

What is the area of the Pacific Ocean in scientific notation?

• 6.378 x 10^7 square miles

• 6.378 x 10^6 square miles

• 6.378 x 10^5 square miles

• 6.378 x 10^8 square miles
