Question

which of the following quantities would be acceptable representations of weight? check all that apply. 12.0 lbs 0.34 g 120 kg 1600 kn 0.34 m 411 cm 899 mn

Explanation:

Step1: Recall weight units

Weight is a force and common units are newtons (N) and its multiples like kN (kilonewtons), MN (meganewtons), and also non - SI units like pounds (lbs). Mass units like grams (g) and kilograms (kg) are not weight units directly, but on Earth, weight $W = mg$ where $g$ is gravitational acceleration. Length units like meters (m) and centimeters (cm) are not related to weight.

Step2: Analyze each option

• 12.0 lbs: Pounds is a unit of weight, so it is acceptable.
• 0.34 g: Gram is a unit of mass, not weight.
• 120 kg: Kilogram is a unit of mass, not weight.
• 1600 kN: Kilonewton is a unit of force (weight), so it is acceptable.
• 0.34 m: Meter is a unit of length, not weight.
• 411 cm: Centimeter is a unit of length, not weight.
• 899 MN: Meganewton is a unit of force (weight), so it is acceptable.

Answer:

12.0 lbs, 1600 kN, 899 MN
