Part 4 a and b and 5 please Read carefully the following selection then answer tihe questions that follow."Since ancient times, wind energy was converted by windmills into rotational kinetic energy in order to grind grain. It was used to raise waterfrom a well.Nowadays, wind energy is also converted into electric energy by aero-generators (nubines).An aero-generator receives, in one second, a wind energy of 28800 J. It comverts 30 % of this energy into electric energy".Questions1. Give the names of two energy conversions mentioned in the text.2. Determine the amount of electric energy produced by the aero-generator in one second.3. Knowing that the average consumption of electric energy by one house is 1080 J in one second, calculate the mumber of houses whose needfor electric energy can be provided by this aero-generator.4. a) When the speed of wind decreases, the above aero-generator can no more provide the same amountof electric energy needed. Why?b) What is then the disadvantage of this wind energy?5. Give two advantages of the wind energy.
