Question

Which of the following measurements is incorrectly expressed?

• A. 2 pa
• B. 15 newton
• C. 9 m/s
• D. 12 cm

Answer 1

The correct option is A 2 pa

While writing a unit named after a scientist we always use capital letters. For example, we write
a) 'N', not 'n' for newton
b) 'Pa', not 'pa' for pascal

All other options are correctly represented.
