Net Kinetic Energy of Electron Solution

Follow our step by step solution on how to calculate Net Kinetic Energy of Electron?

FIRST Step Consider the formula

Q e = J c \cdot (\frac{2 \cdot [BoltZ] \cdot T c}{[Charge-e]})

Next Step Substitute values of Variables

∴

Q e = 0.47A/cm² \cdot (\frac{2 \cdot [BoltZ] \cdot 1350K}{[Charge-e]})

Next Step Substitute values of Constants

∴

Q e = 0.47A/cm² \cdot (\frac{2 \cdot 1.4E-23J/K \cdot 1350K}{1.6E-19C})

Next Step Convert Units

∴

Q e = 4700A/m² \cdot (\frac{2 \cdot 1.4E-23J/K \cdot 1350K}{1.6E-19C})

Next Step Prepare to Evaluate

∴

Q e = 4700 \cdot (\frac{2 \cdot 1.4E-23 \cdot 1350}{1.6E-19})

Next Step Evaluate

∴

Q e = 1093.53922033889W/m²

Next Step Convert to Output's Unit

∴

Q e = 0.109353922033889W/cm²

LAST Step Rounding Answer

∴

Q e = 0.1094W/cm²
