What is the procedure of forming French Government? Write in French. (300 words)-hand written. SCIENCE Make a power point presentation on Sources of Energy You may choose one or two of the following topics to make the presentation. 1. Solar Energy 2. Wind Energy 3. Energy of water 4. Geothermal Energy 5. Waves Energy 6. Tidal Energy 7. Ocean Thermal Energy 8. Nuclear Energy 9. Fossil Fuels Advantages, disadvantages and limitations of these energy sources should be emphasized. More images and data rather than mere words will fetch you higher marks. Cut/Copy/Paste from internet should be avoided. Give credit to the source whenever and wherever it is required. Originality will be one of the parameters while assessing your presentation. You will have a viva based on the PPT. Transfer your PPT in to your email account. This can be downloaded and submitted to the subject teachers when you are called for presentation and viva. HISTORY Compare and contrast the policies of congress and BJP as political parties in India. Gandhi changed the nature of Indian politics between 1920 and 1935. In the light of the above statement discuss his contribution to national movement.
COMPUTERS Create a Power Point Presentation Tutorial to teach How to make an effective and animated Power Point Presentation out in not less than 20 slides. Instructions 1. The presentation should not be a pirated one. 2. The steps that are to be used during the process of making a presentation should be highlighted one after another on each slide. 3. The presentation should have a particular theme. 4. You can use appropriate videos and pictures to represent your point. 5. The video imported in the presentation should be properly merged with the presentation. 6. The presentation should be carried in a pen drive along with the videos and pics imported. 7. In any case if the work is found to be duplicate both the parties would be getting a 0. 8. The minimum number of slide should be 20 in number. MATHEMATICS 1.

SUMMARY LEMMA is a proven statement used to prove other statements Euclid Division lemma says that every number a = b q + r where 0 r b FUNDAMENTAL THEOREM OF ARITHMETIC says that every composite number can be expressed as product of primes and this representation is unique irrespective of the order in which they appear. Theorem 3: If p divides then p must divide q where p and q are prime numbers. Terminating decimal is when denominator is of the form Assignment: POLYNOMIALS 1.
