slug
ounce

1. based on the image, what is the mass of the object being measured?

Explanation:

• Gram: In the metric system, the gram (g) is a fundamental unit for measuring mass. For example, small objects like a paperclip have masses measured in grams.
• Ounce: The ounce is part of the imperial system, not the metric system. It is used to measure mass/weight in countries like the US (e.g., for measuring food items in some contexts).
• Slug: The slug is a unit of mass in the US customary system (related to force \(F = ma\), where \(F\) is in pounds - force, \(a\) in feet per second - squared, and \(m\) in slugs).
• Pound: The pound is a unit of force in the US customary system (though sometimes mis - used as a mass unit in non - scientific contexts), not a metric mass unit.
