The length of a rod measured in an experiment was found to be 2.48m, 2.46, 2.50m and 2.48m and 2.49m, Find the average length , the absolute error in each observation and % error. Q7. A famous relation in physics relates moving mass m to the rest mass m0 of a particle in terms of its speed v and the speed of the light c. A boy recalls the relation almost correctly but forgets where to put the constant c. He writes: m = mo / (1 v2)1/2 Guess where to put the missing c. Q8. A calorie is a unit of heat energy and it equals about 4.2 J, where 1 J = 4.2 kgm2s-2. Suppose we employ a system of units in which the unit of mass equals kg, the unit of length equals m, the units of time is sec. show that a calorie has a magnitude 4.2 -1 -2 2 in terms of the new units.

This appears to be a question so mundane Thinking Outside the Box: Summer Energy Conservation Read the following the information that I collected from the net Its time to say hello to summer and for those of you living in a hot climate like I do, youre also saying a reluctant hello to high summer electricity bills. Most of us already take the standard energy conservation steps, such as setting our thermostat a degree or two higher and using ceiling fans to keep the air circulating, but there are other ways to reduce energy use this summer. If you take a few minutes and challenge yourself to think outside the box, you can brainstorm a bevy of unconventional energy conservation ideas. Here are a few Ive come up with to help you get started! 1. Head underground: If you have a basement, use it. It is cooler underground, which makes the basement the perfect place for a playroom or a study place. You avoid the use of ac and fans thereby saving electricity 2. Air dry your hair: Skip the energy-hogging hair dryers and let your hair naturally dry. For those of us that live in Delhi standing outside for about five minutes should do the trick! A two in one trick of saving electricity and standing in the fresh air. 3. Walk down to burn the fat :If the distance to the market is not very far and is walking distance, you save even more energy because you can leave the car/bike at home. 4. Exercise outdoors: Walking to your local market/coffee shop is one way to conserve energy this summer. If you usually workout at home, whether its walking on the treadmill or exercising to your favorite DVD, head outside a few times a week in the parks and gardens of Delhi! This gets you closer to the natural environment invoking the divine spirit in you. With reference to our mission the fresh air is good for you and youll be minimizing electricity use. 5. Ditch the oven: On the hottest days, avoid using the oven and use your solar cooker outside instead. Again minmising exposure to electromagnetic radiation and saving electricity 6. Plug your outlets: Use child safety plugs in your unused outlets; this will prevent the hot outdoor air from getting in. The benefit of this idea may be nominal but plugging the outlets certainly wont hurt your energy conservation efforts.Similarly avoid metal cupboards and almirahs(or place them in enclosed place) in your bedrooms where you have airconditioners to ensure quicker cooling. A perfect energy saving effort. 7. Cover your terrace with 2,3 sacks in a pile and keep them wet with the water you wash clothes or the outlet of your washing machine(needs planning to instal) and best have a garden water sprinkler (ideal) can maintain the house at much lower temperatures and cool to the effect of an airconditioner. You need to convince your parents for this innovative idea, it should have the cooling effect and does the work of 3 or 4 airconcitioners, provided you are able to use recycled water(water that goes into the drain) 8. By changing the conventional bulbs at home to the LED bulbs the electricity and cost cutting of bulbs become multifolded as these bulbs consume less than one fifth times the electricity as otherwise used by the conventional ones If these ideas have inspired you to think outside the box, Id love to hear your unconventional tips to reduce energy use this summer. Not only hearing you can work on these ideas and implement these and get them when your back after school vacations. Make a project (working model) wherein you can improvise an existing machanism for saving energy or use your creativity to initiate the process of using your basic scientific knowledge to put science in action for saving energy. Channelise your energy and brain power in this OUT OF THE BOX THINKING IDEAS http://www.scjohnson.com/en/green-choices/Conserving-energy/Articles/Article-Details.aspx?date=13-03-08&title=How-Much-Energy-Do-Personal-Care-Appliances-Usehttp://www.scjohnson.com/en/green-choices/Conserving-energy/Articles/Article-Details.aspx?date=13-03-08&title=How-Much-Energy-Do-Personal-Care-Appliances-Usehttp://www.scjohnson.com/en/green-choices/Conserving-energy/Articles/Article-Details.aspx?date=13-03-08&title=How-Much-Energy-Do-Personal-Care-Appliances-UseYour project in Physics/Chemistry could be a very simple practical and innovative idea. Incorporate the basic concepts of Biology, Physics and Chemistry to complete this project. This will be a stepping stone for - may be KVPY Exam or Intel project for CBSE Science fair competition You can work in groups and the size of the group should not exceed 5 CHEMISTRY ECONOMICS Prepare a report supported by suitable images on British Rule in India with respect to its socio-economic and demographic impact.
