Expert in IIT NEET entrance exams

Energy= power×time P =120 W =120 J/s Time t = 20 min = 20×60 second= 1200 second E = 120× 120 = 144000joul E =144×1000 joul =144 kilo joul

POWER=120W TIME=20 min=1200sec Energy=Power*Time E=120W*1200sec E=144000J E=144000J=144Kilojoule

Total energy is the product of power and time... But we have to convert both to the same unit. 20 min= 20*60sec= 1200 sec.. Energy= 1200*120 J =144000 J

120 W is 120 Joules per second, and 20Minutes is 1200 seconds. Hence the total energy consumed is 1200seconds*120W = 144000 Joules or 144 Kilo Joules.

Energy E=P.t where time t in second E=120.20.60=144000 Watt.sec=144000joule E=144 kilojoule

Given: Power=120W Time=t=20min=20X60Sec =1200Sec Power P = Work W ( or Energy E)/ Time taken t Then, Energy E= Power P × Time t So, Energy E= 120 W× 1200sec = 144000 J = 144 KJ.

Silvering of a mirror is the process to convert a plain glass into mirror.After silvering the glass don't allow light to refract through it..So we get a reflecting mirror

Energy consumed will be 120 x 20 x 60 = 144000 J or 144 kJ

Energy = power / time. = 120/120 = 1 Joule
