Question

Cusick drape test on a fabric specimen results in a drape coefficient of 0.7. If the total mass of the paper ring is 3.0 g, then the mass (g) of the paper with shaded area (correct up to 1 decimal place) is ________________.

Hint:

The mass of the paper with shaded area is determined by multiplying the total mass by the drape coefficient.

Answer 1

Correct Answer: 2

The mass of the paper with shaded area is calculated using the formula: \[ \text{Mass of shaded area} = \text{Total mass} \times \text{Drape coefficient}. \] Substitute the given values: \[ \text{Mass of shaded area} = 3.0 \, \text{g} \times 0.7 = 2.1 \, \text{g}. \] Final Answer: \[ \boxed{2.1}. \]
