Answer 1

Answer:

DUDE IT IS A VERY EASY QUESTION.

GIVEN ,

BOTH COOLIES DO THE SAME WORK , LET IT BE X

∆ TIME SPEND BY COOLIE A IS 1 MIN = 60 SEC

THEREFORE , POWER = RATE OF DOING WORK

= WORK / TIME

= X / 60 J

∆ TIME SPEND BY COOLIE B IS 2 MIN = 120 SEC

THEREFORE , POWER = WORK DONE / TIME

= X / 120 J

∆ RATIO OF POWER SPENT = A : B

= X / 60 : X / 120

= 120 : 60

= 2 : 1..............[ ans ]
