Answer question 19 showing fully all the steps. Solution should be simplified and easy to understand as much as possible!

13. in the of but the uses ii) oil is as a energy source. ii. Biomass and fossil fuels are all what is the origin of these resources Biomass i. What is Biomass? 14. The power derived from a windmill is given by the equation er - generator is of diameter 0.6 m and given that the efficiency of the system is 25% at a wind speed of 13.5 ms! P. o p is the average air density, A, the area of the blade and v, the speed of wind; one such 1) Calculate the power output of the aero – generator. Assume that the average air density ja 1.2 kgm3 11) Why is the efficiency of the system less than 40%? 11) State and explain one environmental impact depletion of the ozone layer. iv) Name two greenhouse gases 15. a) Distinguish between renewable and non - renewable energy sources, giving an example of cach b) A solar panel delivers power at the rate of 2.0 kW, when the rays of the Sun fall normally on it.
