Capitolo 1, Problema 59c
Use scientific notation to express each quantity with only base units (no prefix multipliers). a. 4.5 ns b. 18 fs c. 128 pm
Guida verificata passo dopo passo1
Identify the given quantity: 128 pm (picometers).
Recall that 1 picometer (pm) is equal to 10^{-12} meters (m).
Convert the given quantity from picometers to meters by multiplying: 128 pm \(\times\) 10^{-12} m/pm.
Express the result in scientific notation by adjusting the decimal point and the exponent accordingly.
Ensure the final expression is in the form of a single digit before the decimal point followed by the appropriate power of ten.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Scientific Notation
Scientific notation is a method of expressing numbers as a product of a coefficient and a power of ten. It simplifies the representation of very large or very small numbers, making calculations easier. For example, the number 128 can be expressed as 1.28 x 10^2 in scientific notation.

Unit Conversion
Unit conversion involves changing a quantity expressed in one unit to another unit. In this case, converting picometers (pm) to meters (m) is necessary, as scientific notation should only use base units. Since 1 pm equals 1 x 10^-12 m, the conversion is essential for accurate representation.
