Answer 1

The student's question involves completing a table with the correct scientific notation and SI unit prefixes. The prefixes stand for specific powers of 10 and are helpful in expressing numbers in a simplified form in scientific contexts, particularly in physics.

Step-by-step explanation:

The student's question appears to be centered around the understanding of scientific notation and SI unit prefixes for expressing large and small quantities in physics. The prefixes represent certain powers of 10 and are used to simplify numbers. The table should be completed by identifying the correct prefix or exponent associated with the given power of 10. In scientific notation, as shown in Table 1.3, prefixes are used to represent large numbers (positive exponents) or small numbers (negative exponents).

• 1 Pa = 1x100 Pa (No prefix, exponent is zero)
• 1 dPa = 1x10-1 Pa ('d' stands for deci, which represents 10-1)
• 1 mPa = 1x10-3 Pa ('m' stands for milli, which represents 10-3)
• 1 µPa = 1x10-6 Pa ('µ' stands for micro, which represents 10-6)
• 1 nPa = 1x10-9 Pa ('n' stands for nano, which represents 10-9)

For the conversion of standard numbers to scientific notation:

• 101,300 Pa can be written as 1.01 x 105 Pa
• 978.15 m/s can be written as 9.8 x 102 m/s
• 0.000001256 A can be written as 1.256 x 10-6 A
