The strangth of class decreased every year at 10%. If strangth of class was 70000    2 year ago . Find present strangth.

Posted by Rathi Kajal (Mar 20, 2017 11:02 p.m.) (Question ID: 4279)

  • Answers:
  • Ans. Strength of class 2 years ago = 70000

    Decreasing rate = 10%

    Strength after 1 year = {tex}70000 - {70000\times 10\over 100} = 70000-7000{/tex}

    = 63000

    Present Strength = {tex}63000-{63000\times 10\over 100} = 63000-6300{/tex}

    =56700

What's the difference between  foetus and the embryo.

 

Posted by Pratibha Bhatia (Mar 02, 2017 4:53 p.m.) (Question ID: 2912)

  • Answers:
  • When speaking of human development, the term embryo refers to the first eight weeks of pregnancy, while foetus refers to the later stages of pregnancy after eight weeks. 

    The embryonic period is all about the formation of important systems of the body. 

    The foetal period, on the other hand, is more about growth and development so the baby can survive in the outside world.

How can we find the calorific value of a fuel

Posted by Vidushee Sharma (Mar 01, 2017 1:10 p.m.) (Question ID: 2858)

  • Answers:
  • Ans. Calorific value of a fuel can be determined using Bomb Calorimeter. The procedure is explained below.

    The crucible of the calorimeter is filled with the known mass of fuel, and then it is ignited. This heats the surrounding water, and the initial and final temperatures are recorded using a thermometer. The calorific value can be determined using the heat balance. 
    Heat given by the fuel is equal to the heat gained by the water.

Explain the role played by nutrition during adolescence.

Posted by Rathi Kajal (Feb 25, 2017 5:25 p.m.) (Question ID: 2651)

  • Answers:
  • Nutrient needs are greater during adolescence than any other time in the lifecycle. Between the ages of 12 and 18, older children will experience several growing spurts, which are associated with hormonal, intellectual, and emotional changes that can make adolescence a challenging part of life. Failure to consume an adequate diet at this time can result in delayed physical development and growth. Nutrition is also important during this time to help prevent adult diet-related chronic diseases, such as cardiovascular disease, cancer, diabetes, and osteoporosis.
