each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: The extent of adsorption of `CO_(2)` is much more higher than of `H_(2)`. STATEMENT-2: `CO_(2)(g)` has higher critical temperature and more van der Waal's force of attraction as compared to `H_(2)(g)`.
A
if both the statement are TRUE and STATEMENT -2 is the correct explanation of STATEMENT - 1
B
If both the statement are STATEMENT -2 is NOT the correct explanation of STATEMENT -1
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement - 1 : The minimum value of the expression sin alpha + sin beta + sin gamma where alpha, beta , gamma are real numbers such that alpha + beta + gamma=pi , is negative because Statement - 2 : alpha, beta, gamma are angles of a triangle
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement - 1 : The maximum and minimum values f(x) = (1)/( 3 sin x + 4 cos x-2) does not exist Statement - 2 : The given faction is an unbounded function.
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement-1: The equation sin^(2) x + cos^(2) y=2 sec^(2) z is only solvable if sin x =1, cos y=1 and sec z=1 where x, y, z in R because Statement - 2 : Maximum value of sinx and cosy is 1 and minimum value of secz is 1.
