Mean Life Time Solution

Follow our step by step solution on how to calculate Mean Life Time?

FIRST Step Consider the formula

ζ = 1.446 \cdot T 1/2

Next Step Substitute values of Variables

∴

ζ = 1.446 \cdot 0.0002Year

Next Step Convert Units

∴

ζ = 1.446 \cdot 6311.3904s

Next Step Prepare to Evaluate

∴

ζ = 1.446 \cdot 6311.3904

Next Step Evaluate

∴

ζ = 9126.2705184s

Next Step Convert to Output's Unit

∴

ζ = 0.0002892Year

LAST Step Rounding Answer

∴

ζ = 0.0003Year
