Statement-1 : Energy released when a mass of one microgram disappears in a process is `9xx10^(7)J`. Statement-2 : It follows from `E=(1)/(2)m upsilon^(2)`A. Statement - 1 is ture , statement -2 is true, and statement-2 is correct explanation of statement -1.B. Statement-1 if ture, statement-2 is true, but statement -2 is not a correct explanation of statement-1.C. Statement-1 is true, but statement -2 is false.D. Statement-1 is false, but statement-2 is true. |
Answer» Correct Answer - C From `E=mc^(2)`, when `m=1` microgram`=10^(6)g=10^(-9)kg` `E=10^(-9)(3xx10^(8))^(2)=9xx10^(7)J` The statement`-1` is true, but the statement `-2` is certainly false. Choice (c) is correct. |
