Read the information given in the passage and answer the questions that follow. Rockets work differently from the aeroplanes. Aeroplanes use properties of air to fly, but a rocket pushed forward by a jet of hot gases that is produced by burning fuel. Quantity of the fuel burned per second may be as high as a few tonnes per second. All fuels need oxygen to burn. Because rockets have to travel through space where there is no oxygen, they use their own supply in liquid form. The lighter a rocket is, the less fuel it needs. To reduce the weight of space rockets, step rockets are made which drop off the part once the fuel of that part is consumed. Most of the fuel of a rocket is consumed to escape from the gravitational pull of the earth. Once the rocket reaches its escape velocity, it travels fast enough to escape from the earth without burning more fuel. Escape velocity is the speed that an object needs to be travelling to break free of a planet or moon’s gravity well and leave it without further thrust. A rocket leaving the surface of Earth needs to be going 40,320 km/hr to leave without falling back to the surface or falling into orbit. Because of the atmosphere, it is hardly possible to give an object near the surface of the Earth such a high speed. That is why rocket is first placed in low Earth orbit. Rockets are heavy,

Read the information given in the passage and answer the questions that follow. The human body is made up of a large number of chemical compounds, such as water, carbohydrates, amino acids (in proteins), fatty acid (in lipids), and nucleic acids (DNA and RNA). These compounds consist of elements like carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, etc. most of these elements and compounds come from the food. Elements and compounds present in the food are called nutrients. Following is the nutrient information on the packet of two food materials If one gram carbohydrate yields approximately 4 Kcal in the process of respiration. What percent of total calories is from carbohydrate in Food A?
