bag of 20 Kg to a height of 50 cm in 2 and 5 seconds, respectively. (Take g =10 ms?)​

Answer 1

Answer:

power of pahlavi and parul

Answer 2

Answer:

work done to lift the object = increase in potential energy

Parule : workdone = 20×10×0.5= 100 joules

power: 100\5= 20watts

pallavi : workdone = 20× 10 ×0.5= 100 joules

power =100\2=50 watts
