If we take it as " which of the following is not semi conductor then copper and silver both are not semi conductor... So that is wrong.

Corrections!
There are some mistakes in your answers, some of which I am sure about are:
1. C (it's 149.6 which is closer to 150 million Km. It is also the standard) 10. C [Its definitely 36,000 km (35800 to b exact), I guess there is a mistake ..option C shd have been 36000 and not 23000 .. even then i would go with the closest which is C] 13. A or C (Ferrochromite is an ore, while alnico are the alloys of Almunium, Nickel and Cobalt. It is made of Copper wire wound around ferrite i.e. iron core, C would be better option to chose) 15. C (Helium is lighter than Nitrogen with Atomic mass of 4 while Nitrogen has 14, It is used in order to mitigate the toxic effects of Nitrogen under pressure as helium is a Nobel gas, it rarely reacts) 17. C (Bauxite is the answer, Chromite is Chromium's Ore) 24. C (All are Electro Megnectic waves thus would have same spectrum or Speed) I believe rest of your answers are fine and no need to verify them Quote:

Thanks for the wonderful Questions!
Some of the corrections regarding answers that I believe are: 28. C (Dropping body in order to minimize its surface tension turns into spehere) 34. B (Sun must be opposite to you, else light wont b directed to you) 35. C (it is exactly the same as that of earth i.e. 23 hours 56 min and 4 sec) 36. B (LASER, and Maser is microwave based device so that is not possible) 38. B (Common topics: Ozone, Global warming are part of Ecology) 42. A (Once it impacts the earth, it is called then a Meteorite) |

Basic function of kidney is Blood filtration not Execration of urine. It surely involves in urine formation but it is excreted through the urethra not by the kidney itself.
