A spherical gaussian surface encloses a charge of 8.85 x 10 -10C.Calculate the electric flux through the surface. How would the flux change if the radius of the Gaussian surface is doubled and why? Sub: CHEMISTRY Make a list of all the named reactions in chapters from organic chemistry & hydrocarbons & their preparations and write them in your worksheet book. Investigatory project: Disinfectants are substances which are applied on inanimate objects to kill microbes (like floor cleaners) .You can easily prepare a disinfectant on your own. Take a litre plastic bottle. To it add 3 tbsp borax powder & then add 700 ml warm water & shake it well. Then add 4 tbsp of white vinegar & shake to combine. You can add some more things to make it more effective like neem oil, 1 tbsp of liquid dish washer or tea-tree oil .You can search for other methods but do not use any chemical which may be corrosive .Choose a small corner of your house where you can apply it & observe effectiveness. Compare it with the disinfectant you normally use it’s like domex and lizol. Is it more effective ? Justify your answer with arguments. Learn the types of solids and their properties. Note: Use separate A4 size paper for each subject. File them in a stick file and submit on the reopening day. The marks allotted will be considered for TERM- I SEA. See that a cover page with information like TERM- I SEA, Name, Class, Section is also included.
