Question

the mass of a physics textbook is closest to

( 10^1 ) kg

( 10^3 ) kg

( 10^0 ) kg

( 10^{-2} ) kg

Explanation:

Step1: Analyze each option

• \(10^1\space kg = 10\space kg\): A physics textbook is usually a few kilograms, 10 kg is a reasonable estimate for a heavier textbook.
• \(10^3\space kg = 1000\space kg\): This is extremely heavy (like a small car), not possible for a textbook.
• \(10^0\space kg = 1\space kg\): Some light textbooks might be around 1 kg, but many are heavier.
• \(10^{-2}\space kg = 0.01\space kg = 10\space g\): This is too light (like a small notebook), not a textbook.

Step2: Compare with real - world knowledge

A typical physics textbook has a mass that is more likely to be around 10 kg (since \(10^1\space kg = 10\space kg\)) than 1 kg (though 1 kg is possible for a very light one), and much more than 0.01 kg or 1000 kg.

Answer:

\(10^1\space kg\) (the first option: \(10^1\space kg\))
