The pressure of 106 dyne cm-2 is equivalent of _ in SI:
Correct answer: A. 105 Nm-2
- A. 105 Nm-2
- B. 104 Nm-2
- C. 106 Nm-2
- D. 107 Nm-2
Explanation
1 dyne per square centimeter (dyn/cm²) is equivalent to 0.1 pascal (Pa) in the International System of Units (SI).Therefore, 10⁶ dyn/cm² is equivalent to 10⁶ × 0.1 Pa or simply 10⁵ Pa or N/m² in SI units.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
