Answer:
50,625kg of wood
Explanation:
Power input = power output ÷ efficiency
Power output = 7500 horsepower = 7500×750W = 5625000W, efficiency = 6% = 0.06
Power input = 5625000/0.06 = 93750000W
Energy input = power input × time
time = 3hour = 3×3600 = 10800sec
Energy input = 93750000 × 10800 = 1.0125×10^12J
Mass = Energy ÷ Energy density = (1.0125×10^12J) ÷ (20×10^6J/kg) = 50,625kg of wood
