Question

Odd man out from Dyne cm , Kilowatt, Joule ,Erg

Answer 1

Dyne cm

Reason ➡others are already derived from the base units{ kilowatt: joule/sec} {joule: Newton/metre} {erg: dyne*cm}

Hope it helps you:)

Please mark it brainliest..

Answer 2

Answer:

The odd man is Kilowatt.

Explanation:

• Dyne cm: Dyne is the CGS unit of force. force = mass × acceleration

                                                                            Dyne = g × cm/s²

                                                                           Dyne cm = g × cm/s² × cm

                                                                                          = g cm²/s² = erg

          ∴ Dyne cm is also the unit of energy.

• Joule: Joule is the SI unit of  work done or energy .
• Erg: Erg is the CGS unit of energy. 1 erg = $10^-7$ J.
• Kilowatt: Kilowatt = 1000watt and watt is the unit of power. So kilowatt will be the unit of Power.
• Conclusion: Dyne cm , Joule ,Erg - all are unit of energy. But  Kilowatt is the unit of power. So this is the odd one.
