Answer:
<em>12.5watts</em>
Explanation:
Power = Workdone/Time
Since workdone = Force * Distance
Power = Force *distance/Time
Given
Force = 150N
Distance = 10m
Time = 2 minutes = 120seconds
Required
Power
Substitute the given values into the formula;
Power = 150 * 10/120
Power = 1500/120
Power = 12.5Watts
Hence his power is 12.5watts
<em></em>
Answer:

Explanation:
Given that
Temperature of warm water ,T₁ = 25 °C
Temperature of cold water ,T₂ = 5 °C
The maximum possible efficiency of any heat is will be same as the efficiency of the Carnot heat engine.Therefore the maximum efficiency of OTEC system is given as follows
T should be Kelvin scale
Now by putting the values


Therefore the maximum efficiency will be 0.067 or 6.7%.
