Question

The approximate distance from venus to our sun is about 108,000,000 kilometers, a feline hair is about 0.0026 centimeters in diameter. (a) what is the distance from the sun to venus written in scientific notation? (b) what is the diameter of a feline hair written in scientific notation? (c) in comparing the measurements in parts (a) and (b), what else must be done before a comparison is made?

Answer 1

The distance from the sun to Venus can be written as 1.08 × 10^8 kilometers in scientific notation. The diameter of a feline hair can be written as 2.6 × 10^-3 centimeters in scientific notation. The measurements need to be expressed in the same units before they can be compared.

Step-by-step explanation:

a. Scientific notation is used to represent very large or very small numbers. When written in scientific notation, the distance from the sun to Venus, which is approximately 108,000,000 kilometers, would be written as 1.08 × 10^8 kilometers.

b. The diameter of a feline hair, which is about 0.0026 centimeters, would be written in scientific notation as 2.6 × 10^-3 centimeters.

c. Before comparing the measurements in parts (a) and (b), they need to be expressed in the same units. The distance from the sun to Venus is in kilometers, while the diameter of a feline hair is in centimeters. To compare the measurements, you would need to convert one of them to the other unit.
