<span>Wind power is produced from the wind turbines or sails that uses air flow to convert it into mechanical power. It is an alternative to fossil fuel burning, it is all around, renewable, clean, produces no greenhouse gases and uses little land. The advantages of wind power have been greatly praised by many. However, it has disadvantages. Wind power especially at farm is noisy and may spoil the view for their neighboring people. Also the amount of electricity depends on the strength of the wind. If no wind is around, no electricity is produced. </span>

How long was a 60 W light bulb turned on if it used a total of 580 J of energy?
icang [17]
Here's the tool you need.  You can't answer the question without this:

           "1 watt"
means
           "1 joule of energy, generated, used, or moved, every second".

So      60 watts  =  60 joules per second

           Total energy generated,
            used, or moved                  = (power) x (time).

                                     580 joules  =  (60 watts) x (time)

Divide each side
by  (60 watts):              Time  =  (580 joules) / (60 joules/sec) 

                                               =  (9 and 2/3)  seconds  .
