(a) Define the following terms as applied to machines:\n<\/p>\n (i) Load (ii) Effort (iii) Efficiency\n<\/p>\n (b) A load of 500 N is raised through 5 m by a machine when its effort moves simultaneously though a distance of 25 m. If the efficiency of the machine is 80%, calculate its mechanical advantage.\n<\/p>\n 3.(i) State the law of conservation of linear momentum.\n<\/p>\n (ii) Define the term “elastic collision”.\n<\/p>\n (b) A body of mass 8 kg moving with a velocity of 20 m\/s collides with another body of mass 4 kg moving with a velocity of 10 m\/s in the same direction. The velocity of the 8 kg body is reduced to 15 m\/s after the collision. If the bodies do not stick together after the collision, calculate the final velocity of the 4 kg body.\n<\/p>\n 4. Define the following (i) Resistance (ii) Resistivity (iii)\n<\/p>\n (a)State the factors which determine the resistance of a conductor.\n<\/p>\n (b)Find the length of nichrome wire of diameter 0.56 mm which will provide a resistance of100 \u2126 given that its resistivity is 10^-6\u2126m.\n<\/p>\n 5. (a)(i)What are sustainable energy sources?\n<\/p>\n (ii)State four applications of energy generated from water.\n<\/p>\n (b) (i)Define geothermal energy.\n<\/p>\n (ii) Briefly explain how geothermal energy can be harnessed.\n<\/p>\n (c)(i)What is a windmill?\n<\/p>\n (ii) Mention three disadvantages of energy caused by wind.\n<\/p>\n (iii) Does wind itself possess energy?
