Answer :

Power = 100 W


Power is defined as the rate of dissipation of energy. Energy is expressed in Joules.


1 W = 1 Js-1


1 Joule is defined as the amount of energy exerted when a force of 1 N displaces an object by 1m.


1 J = 1 Nm


1 Newton of force can be converted into CGS units. The CGS equivalent is – 1 N = 105 dyne


1 meter is equal to 100 cm.


1 m = 100 cm


1 J = 1 Nm


= 105 dyne × 100 cm


= 107 dyne cm


1 W = 107 dyne cm/s


100 W = 100 × 107 dyne cm/s


= 109 dyne cm/s


1 dyne cm = 1 erg


1 erg = 10-7 J


So 100 W = 109 erg/s
