Question

which object could be measured in both grams and kilograms on a pan balance?
○ large book
○ raindrop
○ tree leaf
○ yarn string

Explanation:

To determine which object can be measured in both grams and kilograms, we analyze the mass of each option:

• A raindrop and a tree leaf are extremely light, typically measured in milligrams or very small grams, not kilograms.
• A yarn string is also very light, usually measured in grams but not likely in kilograms.
• A large book has a mass that can range from a few hundred grams to a few kilograms (e.g., a thick textbook might be around 1 - 3 kilograms, or can be expressed as 1000 - 3000 grams), so it can be measured in both grams and kilograms on a pan balance.

Answer:

A. Large book
