5. Question
1 pointsCategory: Science and TechnologyConsider the following statement
- A geostationary satellite is at an approximate height of 10,000 km.
- FM transmission of music is of very good quality because the atmospheric or man made noises which are generally frequent variation can do little harm.
Which of the statements given above is / are correct
Correct
A geostationary satellite is an earth orbiting satellite, placed at an altitude of approximately 35,800 kilometer (22,300 miles) directly over equator , that revolves in the same direction the earth rotate ( west to each) .At this time altitude , one orbit takes 24 hours , the same length of the as the earth
Require to rotate once on its axis .the term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground base observer
Frequency modulate (FM) transmission has little or no harm from noise compared to amplitude Modulate (AM) transmission. Various electrical disturbance , such as those caused by thunderstorm and automobile ignition system create amplitude modulate radio signals that are received as noise by AM receivers

7. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
- Molasses is a by-product of sugar production process,
- bagasse obtained in the sugar mills is used as a fuel in the boiler to generate steam for the sugar factories
- Sugar can only be produced from sugarcane as the raw material.
Which of these statement are correct ?
Correct
Statement 3 is wrong , sugar can be produced from Sugar Beet also. Sugarbeet is the major contributor for world’s sugar production than sugarcane. Brazil produces sugar from beet sugar.
