Question

the approximate mass of a nickel is: 0.5 kg, 0.005 kg, 0.0005 kg, 5 kg

Explanation:

Step1: Recall nickel's mass in grams

A nickel (US coin) has a mass of about 5 grams.

Step2: Convert grams to kilograms

Since \(1\,\text{kg} = 1000\,\text{g}\), convert 5 grams to kilograms: \(5\,\text{g}=\frac{5}{1000}\,\text{kg}=0.005\,\text{kg}\).

Step3: Compare with options

Check the options: \(0.5\,\text{kg}\), \(0.005\,\text{kg}\), \(0.0005\,\text{kg}\), \(5\,\text{kg}\). The correct conversion gives \(0.005\,\text{kg}\).

Answer:

0.005 kg (the option with "0.005 kg")
