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

Correct Answer: 2
Solution and Explanation
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:
\[
\boxed{2.1}.
\]
