Question

11. A man can do work at the average rate of 10 watt. How many bricks
he can carry per hour from bottom to the roof of a house of height 10
metre ? (mass of each brick = 3kg and g = 10m/sec2}
​

Answer 1

TOTAL WORK = MGH = 3×10×10 =300 JOULE

POWER = 300/ 1HR = 300 /60×60 = 3/36 = 1/12 WATT

N ×1/12 = 10

N = 120 ...BRICKS ....

Answer 2

Step-by-step explanation:

Total work = MGH = 3 × 10 × 10 = 30 joule ( J)

Power = 300 / HR = 300 / 60 × 60 = 3 / 36 = 1 / 12 Watt ( W)

N × 1 /12 = 10

N = 120
