Question

The distance between the sun and earth is about 1.5x10^11 m. Express this distance using at least 4 differnt prefix.

A) 150×10^9 km
B) 150×10^11 mm
C) 150×10^6 Mm
D) 150×10^3 Gm
E) all of the above

Answer 1

The distance between the sun and earth can be expressed using different prefixes such as kilometers, millimeters, megameters, and gigameters.

Step-by-step explanation:

The distance between the sun and earth is 1.5x10^11 m. To express this distance using different prefixes:

A) 150x10^9 km: To convert meters to kilometers, divide by 1000. This gives us 1.5x10^8 km, which can be written as 150x10^6 km or 150 million km.

B) 150x10^11 mm: To convert meters to millimeters, multiply by 1000. This gives us 1.5x10^14 mm, which can be written as 150x10^12 mm or 150 trillion mm.

C) 150x10^6 Mm: To convert meters to megameters, divide by 1,000,000. This gives us 150x10^3 Mm or 150,000 Mm.

D) 150x10^3 Gm: To convert meters to gigameters, divide by 1,000,000,000. This gives us 150 Gm.

Therefore, the correct answer is E) all of the above, as they all express the distance between the sun and earth using different prefixes.
